Complexes of tin, antimony, silicon, germanium, iodine, boron and titanium halogenides with organic ligands were investigated using nuclear quadrupole resonance (NQR) and X-ray fluorescence spectroscopies, and Moessbauer effect and quantum-chemical calculations.A discussion of results which we obtained previously as well as literature data is included.The correlations between 35Cl NQR and ClKα line shifts in SnCl4L2, SbCl5L and TiCl4L2 complexes were obtained.The geometry of the acceptor was found to influence the value of the effective charge on the chlorine atom (qCl) in SnCl4L2 complexes, but not to influence the chlorine atom in TiCl4L2 complexes.Values of qSn and qSb were calculated from Moessbauer isomer shifts in the SnCl4L2 and SbCl5L complexes.Electron-density transfer from the ligand to the vacant d orbital of the central atom on complexation was observed.

The previously reported mixed ligand compound SnCl4(DMF)(DMSO) (DMF = NN-Dimethylformamide, DMSO = Dimethylsulphoxide) has been studied by IR, Raman and Moessbauer spectroscopy.Our results confirm its homogeneity with the DMF and DMSO ligands coordinating
