Abstract

A zigzag chain structural compound named Ni_0.5{[Ni(en)] ₂[Ni(en)(H₂O)]₂[H₃NiMo ₆W₆O₄₀]}•3H₂O 1 (en = ethylenediamine) was hydrothermally synthesized and characterized by IR, TG and X-ray diffraction analysis. Structural analysis indicates that compound 1 exhibits an unusual Mo/W mixed Ni^II centered Keggin structure, which is tetra-capped by two [Ni(en)]²⁺ and two [Ni(en)(H ₂O)]²⁺ units. Two linkages of M-O-Ni(2) and M-O-Ni(4) connect two adjacent tetra-capping clusters in different directions, and it represents a novel inorganic-organic zigzag chain built on the Ni^II centered Keggin species. Compound 1 is demonstrated to be a high selectivity for benzaldehyde in the oxidation of styrene, while the magnetic data of complex 1 were fitted to the Curie-Weiss law and show antiferromagnetic interactions.
