2-Aminothiazole, acetylaminothiazole, dimethylhydantoin and thiohydantoin complexes of tin(IV) and titanium(IV) halides

Abstract

Complexes of the type MX₄L₂ (M = Sn, Ti; X = Cl, Br, I; L = dimethylhydantoin, thiohydantoin, 2-aminothiazole and 2-acetylaminothiazole) have been prepared and characterized. Infrared spectral studies indicate exocyclic nitrogen of 2:aminothiazole and carbonyl oxygen of all other ligands as the donor site. Far-infrared spectra suggest that dimethylhydantoin and 2-acetylaminothiazole complexes are trans, and 2-aminothiazole and thiohydantoin complexes are cis octahedral.
