Template Synthesis of Tin(IV) Complexes with Tridentate Iminopyridine Ligands

Abstract

Six-coordinate metal complexes containing tridentate Schiff  bases with an ONN-chelating moiety were prepared by template synthesis on tin tetrachloride using various aminophenols and α-carbonyl-substituted pyridines. The structures of five compounds were studied by X-ray diffraction (CIF files CCDC nos. 849152–1849156). The UV/Vis spectra of the obtained series of compounds were found to be highly sensitive to the nature of substituents in the moieties of organic ligand.
