Group VI dinuclear oxo metal complexes of salicylideneimine-2-anisole Schiff base

Interaction of the Schiff base salicylideneimine-2-anisole (salanH) with Cr(CO)(6) yielded the dicarbonyl derivative Cr2O2(CO)(2)(salan)(2). The dinuclear oxo complex M2O4(salan)(2), M = Mo and W, was isolated from the reaction of M(CO)(6) with salanH. Elemental, spectroscopic and magnetic studies of the reported complexes allowed structures to be proposed. The thermal properties of the complexes were investigated by thermogravimetry.
