The series of titanium (IV) complexes trans-[TiCl4(OPPh3)2] (1), trans-[TiBr4(OPPh3)2] (2) and trans-[TiI4(OPPh3)2] (3) were obtained as polycrystalline powders by heating the corresponding metal tetrahalides with triphenylphosphine oxide in evacuated sealed glass ampoules. The crystal structures were determined by single crystal X-ray diffraction. Compounds 1 and 2 were isolated as yellow and brown crystalline powders, with yields 70 and 75%, respectively. This paper discusses the synthesis of these coordination compounds 1–3 and their crystal structures, and analyzes the geometric parameters of the related molecular complexes of niobium and rhenium for use in the design of magnetically diluted systems.
