Abstract
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.
期刊介绍：
Inorganica Chimica Acta is an established international forum for all aspects of advanced Inorganic Chemistry. Original papers of high scientific level and interest are published in the form of Articles and Reviews.
Topics covered include:
• chemistry of the main group elements and the d- and f-block metals, including the synthesis, characterization and reactivity of coordination, organometallic, biomimetic, supramolecular coordination compounds, including associated computational studies;
• synthesis, physico-chemical properties, applications of molecule-based nano-scaled clusters and nanomaterials designed using the principles of coordination chemistry, as well as coordination polymers (CPs), metal-organic frameworks (MOFs), metal-organic polyhedra (MPOs);
• reaction mechanisms and physico-chemical investigations computational studies of metalloenzymes and their models;
• applications of inorganic compounds, metallodrugs and molecule-based materials.
Papers composed primarily of structural reports will typically not be considered for publication.
