Complexation of titanium n-butoxide Ti(OBun)4 and zirconium n-butoxide Zr(OBun)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 wellknown 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 H-1-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.
