also has some of the character of a textbook, it can serve as an introduction to
the subject for novice pigment users or
pigment developers, most of who subsequently keep it to hand as a valuable reference source.
Many of the products described in
this book have had a firm place in the
market for several decades. As in previous editions, these pigments make up
the largest part of the work. This comprehensive survey of the chemistry of
the pigments, including details of their
special properties for technological
applications, gives the reader a unique
means of entry into the labyrinth of coloring materials.
The first chapter deals with general
fundamental principles and scientific
and technical concepts. Following that,
the book describes practically the
whole range of methods and tools available to the color chemist or pigment
developer: the design of the chromophore, aspects of crystal engineering,
and crystallization techniques for producing particles of suitable size and morphology. Methods for the physical characterization of pigments and for determining color fastness and other properties are described, including the interpretation of data from measurements,
and there is a detailed discussion of dispersion properties and conditions affecting color. However, the literature citations in this chapter are centered
around about 1975—readers would
have appreciated being given more upto-date references.
The grouping of pigments according
to their chemical structural classes is a
convenient system, which is easy for
the reader to follow. The authors have
devoted much attention to azo pigments,
a field in which they have special expertise, and they provide a uniquely
detailed account of the development of
this class of pigments, which has more
branches and ramifications than any
other. The list of the most important
classes of pigments covered in the
book also includes isoindolines, isoindolinones, phthalocyanines, quinacridones,
perylenes, diketopyrrolopyrroles, dioxazines, and anthraquinones.
For each class of pigments the
authors explain the structural principle,
and describe the history of its development, structure–property relationships,
4394
methods of synthesis, and lastly the general properties and areas of application.
The applications-related properties of
individual pigments within the class are
then described in detail in accordance
with their economic importance. Altogether, the work provides the pigments
user with a wide-ranging survey of the
properties of several hundred pigments,
in a form that is independent of their
manufacturers and trade names.
The book concentrates exclusively
on pigments that are in commercial use
for conventional decorative applications
as coloring agents in paints and lacquers,
plastics, and printing inks. This aspect is
covered comprehensively. Other areas
of application of pigments, whether for
color properties (e.g., in color filters),
for other functions (e.g., as photoconductors), or in new concepts (e.g.,
latent pigments) are not covered.
This third edition of “Herbst and
Hunger” remains true to its genre,
which is between a textbook and a
work of reference. There is no other
comparable book that covers the physical fundamentals, chemistry, and applications properties of organic pigments
so comprehensively, and in so compact
and attractive a form.

Metal–Ligand Bonding
By Bob Janes and
Elaine Moore. Royal
Society of Chemistry, Cambridge

In Metal–Ligand Bonding, which is
based on part of a course at the Open
University in Great Britain (http://
0 2004 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim
www.angewandte.org
www.open.ac.uk) and is published by
the Royal Society of Chemistry, Bob
Janes and Elaine Moore give an excellent description of the theoretical fundamentals of the bonding of ligands to
transition metals. It is intended for
beginners in coordination chemistry,
and is written in a way that makes it
easily accessible to such readers. Starting from d orbitals, the reader works
through the topics of crystal- field
theory, UV/Vis spectroscopy, magnetism, and finally molecular orbital
theory applied to transition-metal complexes. Although many textbooks of
inorganic chemistry devote one or
more chapters to these topics, this little
book differs from them, insofar as it
serves as an excellent bridge between
simpler treatments of coordination
chemistry and those that are more
detailed and advanced.
The book has a very good didactic
structure, and it is a pleasure to work
through it. Although it consists of only
104 pages, all the recently introduced
ideas are explained, and often illustrated
by examples. The authors even find
space to explain the secret of the Lifschitz salts, and to mention research on
special tetrahedral complexes. The text
is illustrated by clearly drawn figures
throughout, many in color, and there
are also a few photographs of experiments. All the longer chapters end with
a summary of the contents, and there is
a list of learning objectives at the end
of the book. The reader=s learning achievements are tested by various exercise
problems. These are given in the forms
of questions and answers linked directly
to the text, problems at the end of each
section, and a comprehensive final test
paper at the end of the book. Detailed
answers to all the problems are given
in the appendix.
However, I was not so pleased to
find that there are no literature references, not even to more advanced books
on coordination chemistry. Also I
found the chapter on magnetism too
compressed in comparison to the other
chapters. Here it would have been
better to explain the points more fully,
especially at the beginning of the chapter. In the detailed treatment of the
theory of magnetic and spectrosopic
properties, I would have liked to see
short discussions of the spin-crossover

phenomenon and of inorganic photochemistry (including the luminescence
of transition metal complexes such as
[Ru(bipy)3]2+).
This book can be recommended
unreservedly as an introduction to coordination chemistry. One can get a preliminary impression of it by visiting the

Web site www.rsc.org/metalligand,
where some parts of the book can be
downloaded as PDF files: Chapter 14
(“Charge-Transfer Bands in the Electronic Spectra of Transition-Metal Complexes”), a list of the learning objectives,
and—especially pleasingly—all the figures.
