ResumoA bimetallic isopropoxide of cobalt(II) with the formula Co[Zr2(OPri)9]2, prepared by the reaction of COCl2 with K[Zr2(OPri)9] in 1:2 molar ratio, has been shown to undergo alcoholysis reactions with graded alcohols (primary, secondary and tertiary) to afford products of the types, Co[Zr2(OR)9]2 (where R = Me, Et, Prn, Bun, Bui and Bus) Co[Zr2(OPri)3(OEt)6]2, Co[Zr2(OPri)6(OBus)3]2, CO[Zr2(OPri)3(OBus)6]2, Co[Zr2(OPri)6(OBut)3]2 and Co[Zr2(OPri)3(OR)6]2 (where R = Amt or But). These derivatives have been characterized by elemental analyses and molecular weight determinations. Infrared, electronic (visible) spectral and magnetic susceptibility measurements suggest a distorted octahedral geometry for these derivatives.
