摘要：
Planar, isolated anions SiP 35−, SiAs 35−, GeP 35− and GeAs 35− are present in the crystals of the dark, shiny metallic title compounds (Zintl phases). The 24‐valence electron units are the first examples of CO 32− ‐isosteric anions in which central atoms and ligands belong to higher periods. Bond orders (after Pauling) of 1.22, 1.28, 1.12 and 1.26, respectively, can be derived from the measured bond lengths. Copyright © 1990 by VCH Verlagsgesellschaft mbH, Germany
