Bis([mu]-2-hy­droxy­methyl-2-methyl­propane-1,3-diolato)bis­[di­chlorido­titanium(IV)] diethyl ether disolvate

A. J. Nielson, C. Shen and J. M. Waters

Abstract: The title complex, [Ti2Cl4{CH3C(CH2O)2(CH2OH)}2], lies across a centre of symmetry with a diethyl ether solvent mol­ecule hydrogen bonded to the -CH2OH groups on either side of it. The TiIV atom is coordinated in a distorted octa­hedral geometry by a tripodal ligand and two terminal chloride atoms. There are three coordination modes for the tripodal ligand distinguishable on the basis of their very different Ti-O bond lengths. For the terminal alkoxo ligand, the Ti-O distance is 1.760 (1) Å, the asymmetric bridge system has Ti-O bond lengths of 1.911 (1) and 2.048 (1) Å. The Ti-O bond length for the alcohol O atom is the longest at 2.148 (1) Å.
