Bis(μ-2-hy-droxy-methyl-2-methyl-propane-1,3-diolato)bis-[di-chlorido-titanium(IV)] diethyl ether disolvate

The title complex, [Ti2Cl4{CH3C(CH2O)2(CH2OH)}2], lies across a centre of symmetry with a diethyl ether solvent mol-ecule hydrogen bonded to the -CH2OH groups on either side of it. The Ti(IV) atom is coordinated in a distorted octa-hedral 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.
