Book Review Transition Metal Chemistry. Edited by R. L. Carlin

gounding on a given class of substances. As can be seen
from the contents, the work is intended for the advanced
reader, so that the discussion of general problems could well
have been shortened as e.g. in the case of deamination (Vol.1,
p. 36) or the nitration mechanism (Vol. 2, p. 436). Instead,
the author might profitably have provided a n introductory
chapter on bond lengths, energy relationships, hybridization,
(’re. in nitrogen compounds.
The printing errors, which are particularly common in the
first volume, should be corrected in future editions. With
a little effort it should also be possible to present many of
the structural formulae in a clearer form.
Apart from these small defects, the author has succeeded in
presenting a comprehensive survey of the chemistry of openchain organic nitrogen compounds that restricts itself to the
description of the functional groups containing nitrogen. It
is to be hoped that the work will find a wide audience.

Transition Metal Chemistry. Edited by R . L. Cnrlin. Vol. 1
Marcel Dekker, Inc., New York 1966. 1st Edit., xi, 307 pp.,
numerous figures and tables, cloth 5 12.75.
The present volume begins what should become a very useful
series of short monographs o n current problems in the field
of transition metals. As is shown by a preview of the contents
of future volumes, recognized experts will report not only o n
questions concerned purely with coordination chemistry, but
also on special physical and biological results in connection
with the transition metals.
I n the first chapter ( R . L. Cnrliii, 32 pp.) of the present work,
the electronic configuration and molecular geometry of a
wide range of CO(II)complexes are discussed o n the basis
of the ligand field theory and with the aid of spectroscopic
and magnetochemical results. A well written section by H. B.
Grtry (49 pp.) deals with the electronic structure of squareplanar metal complexes from a similar point of view. After
an introduction on bonding mechanism and electronic spectra
in simple complexes of the type [MIrL4]2-, the section deals
in particular with the recently discovered systems having
bidentate hgdnds containing sulfur and which are stabilized
i n a rigidly planar conformation.
Another article ( J . E. EtirIey and R . D . Ctmnon, 77 pp.) is
concerned with the coordination chemistry of the Cr(m) ion
in aqueous systems. Finally, special mentisn should be made
of the excellent section on “Hydrido complexes of transition
metals” ( A . P . Grinsberg, 127 pp.), which presents a systematic survey of practically all molecules and ions of the type
H;M,Lk (1, = any Iigand, k 0)known up to February 1965
that contain B direct M-H bond. I n accordance with the
definition, for I( = 0 the section only deals with ions of the
general formula jMjHi]. In addition to preparative techniques, the author presents a particularly critical discussion o
the structure of these complex hydrides and the M-H interaction.
The volume is richly provided with references, and has a
good author- but a rather poor subject-index. It is not only
;L progress report, but also can be recommended to anyone
who is interested i n modern inorganic chemistry, both as an
introduction and for further study. Th. Kruck [NB 546 IEI

Modern analysis makes wide use of physical methods. The
physical effects on which these methods are based are so numerous that there is a considerable need for textbooks, monographs, or reviews. However, textbooks in particular satisfy
only in part the readers information requirements. Though
they generally describe the theoretical basis of the method
Arigc’w. Cliein. interntit. Edit.

and the principle of the apparatus used, too little space is
given to applications to the various classes of substances and
to the discussion of special techniques. Finally, most textbooks are outdated by the time they are read, and owing to
their limited scope, fail to give the reader the answers to the
very questions in which he is interested.
The “Advances in Chromatography”, the first volume of
which contains four contributions on liquid-phase chromatography and six on gas chromatography, d o not exhibit these
disadvantages to the same extent as conventional textbooks.
Specialists were asked to write on narrowly limited topics
in the hope that the authors would give a picture, even subjective, of the current state of development. Accordingly.
nearly all the chapters in the firsi volume are interesting and
stimulating. The content of new Information of practical
value is high. The theoretical and practical aspects of the
techniques under discussion are well presented by the authors.
Thus the reader of the Advances” is spared the complete
study of the otiginal literature, and i s nevertheless acquainted
with the latesr position and the tfend of the development of
the metmids in question. The fact that the individual articles
bear little relation to one another detracts little from the
value of the book. However, the reader of the chapters on
gas chromatography will generally not be so interested in
those on liquid chromatography, and vice versa. The editors
are to be congratulated on their project and the authors on
the articles in the first volume, and it is to be hoped that
future volumes can also d o justice t o the editors’ intentions.

Dynamics of Chromatography. Part 1. Principles and Theory.
By J . C. Giddings. Series of monographs: Chromatographic
Science, Vol. 1. Marcel Dekker, Inc., New York 1965.
1st ed., xii, 323 pp., numerous illustrations, bound 511.50.
The first six chapters present a step-by-step build-up of the
general dynamic theory of chromatography as applied to the
behavior of the zones, and in particular to the changes in the
zone profiles in column chromatography. The seventh chapter alone is devoted to the problems of the actual separation.
The author never fails to indicate the relationships between
theory and experiment.
The formulae are carefully chosen and clearly listed at the
end of the book. One defect, which could easily be rectified
in a later edition, is the absence of section numbers at the
top of each page. A pleasing feature of the book is the
extensive list of references at the end of each chapter, though
it must be admitted that practically no recent Germanlanguage literature is included.
This book, like the other well-known works on the fundamentals of chromatography, is indispensable to anyone who
wishes to penetrate more deeply into this field and who seeks
a new approach. It is outstanding for its lucidity of expression and its accurate mathematical formulations without
making too heavy demands on the reader’s mathematical
knowledge.
There are so many elementary physical processes underlying
the chomatographic procedures1 that it seems hopeless to
build up a theory that offers a qua,ntitative approach to all
chromatographic phenomena \rihich can be utilized in
practice. Of thd various theoretical models. the conventional
“discontinuous p k e model is not acceptabllein the author’s
view. The author is not entirely consistent, since he nevertheless regards the conventional concept of plate height,
which is used to characterize the chromatographic separating
power, as indispensable. In the reviewer’s opinon, this inconsistency is one shortcoming of this book, but probably
the only one.
On the whole, this is a thorough and interesting treatment
of general chromatography ; we must therefore wait expectantly to find what results will be achieved by its application to gas chromatography (Vol. 2) and t o liquid-phase
