The title compound, octa-tert-butoxybis[micro(3)-2,2'-(N-methylimino)diethanolato]di-micro-oxo-tetratitanium(IV), [Ti(2)O[(OCH(2)CH(2))(2)(NCH(3))][(CH(3))(3)CO](4)](2) or [Ti(4)(C(5)H(11)NO(2))(2)(C(4)H(9)O)(8)O(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 (t)BuO(-) 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) A, while the Ti-N bond length is 2.374 (2) A.
