AbstractA family of triethanolamine complexes of titanium with varying metal/ligand ratios have been prepared from reactions of titanium tetraisopropoxide with triethanolamine. Three nonhydrolytic products, having essentially all isopropoxide ligands substituted by triethanolamine, were prepared as hygroscopic, glassy solids. Crystals of two hexameric titanatrane partial hydrolysis analogues [Ti 3(μ 2-O) {(HOCH 2CH 2) 2NCH 2CH 2O} {(OCH 2CH 2) 2(μ 2 -OCH 2-CH 2)N} 2{(OCH 2CH 2) (μ 2-OCH 2CH 2) 2N}] 2(1), and [Ti 3(μ 2-O) {OCH(CH 3) 2}{(OCH 2CH 2) 2 (μ 2-OCH 2CH 2)N} 2 {(OCH 2-CH 2)(μ 2-OCH 2 CH 2) 2N}] 2 (2) were isolated and structurally characterized. The structures consist of a central core of two oxo-bridged dititanatranes (TEA)TiOTi(TEA) (TEAH 3 = triethanolamine) with the nonhydrolytic residue (TEA)Ti(TEAH 2) included as an adduct in (1), analogously to (TEA)Ti(OPr i) in (2).
