Description:
In recent years, crystalline polyoxotitanium clusters (PTCs) have attracted increasing attention as a new kind of promising crystalline material. In this work, a PTC stabilized by phenylphosphonate ligands, i.e. hexa-μ-isopropanolato-hexaisopropanolatodi-μ3-oxido-hexa-μ3-phenylphosphonato-heptatitanium tetrahydrate, [Ti7(μ3-O)2(O3P-Phen)6(OiPr)12]·4H2O [PTC-54; H2O3P-Phen is phenylphosphonic acid, C6H5PO(OH)2, and HOiPr is isopropanol, C3H7OH], was obtained successfully through a facile one-step solvothermal reaction. The dumbbell-like core structure of PTC-54 can be described as two trinuclear {Ti3(μ3-O)} building units combined together by six phenylphosphonate ligands and one additional Ti atom, giving rise to a Ti7 cluster. Adjacent molecules of PTC-54 are further connected through π–π interactions between the phenyl groups to form a supramolecular one-dimensional chain.
