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.
