Crystal chemical analysis of naphthalene-1-, naphthalene-2-, and anthracene-9-carboxylate-containing complexes of 3 metals was performed within the framework of a stereoatomic model of crystal structure using the characteristics of Voronoi-Dirichlet polyhedra. The types of coordination of naphthalene-1-, naphthalene-2-, and anthracene-9-carboxylate anions with respect to 3 metals are considered. The influence of the type of coordination on the characteristics of connections M–O in crystal structures is revealed. The 18-electron rule is used to quantify the electron-donating ability of naphthalene-1-, naphthalene-2-, and anthracene-9-carboxylate anions with respect to 3 metals, which decreases steadily from left to right. With respect to two-row 3 metal ions, correlations have been established between the electron-donating ability of oxygen atoms of naphthalene-1-, naphthalene-2- and anthracene-9-carboxylate ions and the group number in which the 3 metal is located.
