Abstract

The reaction of [Na₁₂(H₂O)₃₈][WZn{M(H ₂O)}₂(ZnW₉O₃₄)₂] ·3H₂O (M = Mn, Co) and Co(NO₃)₂· 6H₂O in water at 80 °C afforded red crystals of [Co(H ₂O)₆]₂{[Co(H₂O)₄] ₂[Co(H₂O)₅]₂WZn[Co(H ₂O)]₂(ZnW₉O₃₄)₂} ·10H₂O (1), which has been characterized by TGA, IR, PXRD, element analysis and single crystal X-ray diffraction. The polyanion [WZn{Co(H₂O)}₂(ZnW₉O₃₄) ₂]^12- in 1 is double-linked by cobalt(ii) cations to extend into a 1D anionic polymeric chain of {[Co(H₂O) ₄]₂[Co(H₂O)₅] ₂WZn[Co(H₂O)]₂(ZnW₉O ₃₄)₂}^4- with partial free cobalt cations. The redox active cobalt(ii) sites made compound 1 an excellent catalyst for the oxidation of styrene with high styrene conversion (up to 96%) and high benzaldehyde selectivity (up to 99%).
