The 35Cl NQR frequency changes in the MCl4L and MCl4L2 (M = Si, Ge, Sn, and Ti) complexes are analyzed. The atomic orbital populations are calculated for Si, Ge, and Sn at the PM3 level and for Ti at the MNDO level. The results obtained allow one to explain the complexation-induced changes in the 35Cl NQR frequencies and asymmetry parameters. A decrease in the 35Cl NQR frequency of the non-transition-element complexes is mainly due to the increase in population of the chlorine atomic pz orbitals. With the titanium complexes, an increase in the 35Cl NQR frequencies is explained by the weakening of the pπ-dπ electron-density transfer.
