The synthesis and structural features of some organosilicon (IV) complexes with Schiff bases derived by condensing Substituted benzaldehyde with o-aminothiophenol have been discussed. The newly synthesized compounds have been characterized by elemental analyses, IR, 1H, 13C, and 29Si NMR spectral studies. With the help of spectral studies, penta, and hexacoordinated environments around the central silicon atoms in the 1: 1 and ...
