Results are presented of comparing the thermodynamic properties of the bivalent metal aquo and amino complexes (gaseous state, T = 18°C) of general formula [MLm]2+ (M = Cu, Ni, Mg, Ca, Sr, Ba, Zn, Mn, Fe, Co, and Be; L = H2O and NH3; m = 2, 4, and 6) with the structural index, which is calculated by simulating the random mutual orientations of the steric models of these compounds. For the aquo complexes, the correlations between the heats of formation from elements and the index are found for the structural classes specified by the coordination numbers 2, 4, and 6; the coefficients of correlation r are -0.983, -0.979, and -0.985, respectively. The general correlation relationship between the index and the heat of formation from gaseous M and L is obtained for the amino complexes (n = 16, r = 0.987, σ = 7%).
