LiSr2 [ReN4 ] and LiBa2 [ReN4 ] – Isotypic Nitridorhenates(VII).
—
16 - 002 Colorless crystals of the title compounds are◦ prepared by reaction of the
constituent metals with flowing N2 (850–900 C, 60 h). Single crystal XRD
reveals that they crystallize in the monoclinic space group P21 /m with Z = 2.
In their crystal structures the motif of the InNi2 -type structure is formed by
the M (M: Sr, Ba) atoms and nitride ions. M is trigonal prismatic coordinated
by N. One half of the tetrahedral voids within the partial structure formed by
stacking of trigonal prismatic rod layers is occupied by Re and Li is located on
the remaining tetrahedral sites. — (HOCHREIN, OLIVER; BORRMANN,
