Abstract

Stoichiometric reactions of pyridine-2-aldoxime (HL1) with titanium 2-propoxide and of salicylaldoxime (H(2)L2) with titanium 2-propoxide or titanium ethoxide in toluene at room temperature resulted in the formation of Ti-2(mu-O)(mu-L)(2)(OR)(4) (for L1, R = Pr-i; for L2, R = Pr-i or Et). These complexes were all characterized by spectroscopic methods; in addition, the molecular structure of Ti-2(mu-O)(mu-L1)(2)((OPr)-Pr-i)(4) was determined by single-crystal X-ray diffraction. The titanium atoms have distorted octahedral geometries that share an apex through a bridging oxygen. Each monoanionic L1 is chelated to one titanium atom through its pyridine and oximate nitrogen atoms and to a second titanium atom through its oximate oxygen atom.
