AbstractThe title compound, octa-tert-butoxybis[μ 3-2,2′-(N-methylimino)diethanolato] di-μ-oxo-tetratitanium(IV), [Ti2O{(OCH2CH 2)2(NCH3)}{(CH3)3CO} 4]2 or [Ti4(C5H11NO 2)2(C4H9O)8O 2], lies about an inversion centre, and displays the less usual zigzag configuration. One O atom of the N-methyldiethoxoamine ligand bridges the symmetry-related Ti atoms, while the other bridges the two independent Ti atoms, with the N atom binding to give a facial configuration. Four tBuO- ligands and a bridging oxide complete the respective five- and sixfold coordination of the two Ti atoms. The Ti-O bond lengths range in a self-consistent fashion from 1.7624 (17) to 2.0878 (18) Å, while the Ti-N bond length is 2.374 (2) Å.
