Complexation of Titanium n-butoxide Ti(OBu n )4 and Zirconium n-butoxide Zr(OBu n )4 with Some Oxime Ligands and Structural Analysis of the Complexes

Titanium tetra-n-butoxide, Ti(OBuⁿ)₄, and zirconium tetra-n-butoxide, Zr(OBuⁿ)₄, were reacted with some well-known dioxime and monoxime ligands such as dimethylglyoxime (DMG), salicylaldoxime (SO) and acetone oxime (AO). The structures of the resulting complexes have been determined by elemental analysis, i.r. and ¹H-n.m.r. spectroscopy. The complexation ratio of both Ti(OBuⁿ)₄ and Zr(OBuⁿ)₄ was found to be 1:2 with DMG and SO. On the other hand, both 1:1 and 1:2 complexation ratios of the same metal alkoxides were observed with the ligand AO.
