Abstract
The following coordination complexes of titanium (IV) have been prepared: TiCl4•2CO(NH2)2, TiCl4•CO(NHCH3)2, TiCl4•2CO(NHCH3)2, 2TiCl4•2NH2CON(C6H5)2, 2TiCl4•2CO(NHC6H5)2 TiCl4•2CS(NH2)2, 2TiCl4•CS(NHC2H5)2, 2TiCl4•NH2CSN(C6H5)2, and 2TiCl4•CS(NHC6H5)2; their infrared spectra have been measured and their molecular weight determined. For urea and its derivatives the coordination to titanium (IV) is always through the oxygen atom. The phenyl derivatives of urea led to dinuclear complexes which were best explained by assuming halogen bridging between the titanium atoms. Thiourea and its derivatives gave complexes in which coordination occurred through one of the nitrogens in the case of thiourea and through both nitrogens in the case of the derivatives. Halogen bridging was again assumed to explain the formation of the dinuclear complexes.Keywords
