Crystallochemical Role of Benzoate and Phenylacetate Ions in Structures of Coordination 3 d -Metal Compounds

A crystal chemical analysis of the 3 d -metal benzoate- and phenylacetate-containing compounds is carried out in terms of the stereoatomic crystal structure model using characteristics of the Voronoi–Dirichlet polyhedra. Coordination types of benzoate and phenylacetate anions toward the transition metals from Ti to Zn are considered. The influence of the coordination type on the characteristics of M–O bonds in the crystal structures is revealed. The electron-donating ability of benzoate and phenylacetate anions toward 3 d metals is quantitatively estimated using the 18-electron rule.
