【摘要】A novel molybdenum(Ⅴ) phosphate decorated with nickel complex

cations,

Ni[Mo6O12(OH)3(PO4)(HPO4)3]2-(bipy=2,2'-bipyridyl),

been

[Ni(H2O)2][Ni(H2O)(bipy)2]4·5H2O

hydrothermally synthesized and characterized by IR, TGA and single-crystal X-ray diffraction. Two {Mo6P4} clusters are linked via one Ni cation to form a Ni[Mo6P4]2 dimer unit, which is further connected together by additional nickel coordination complex ions to give 1-D molybdenum(Ⅴ) phosphate chain-like structure. A probe reaction of the oxidation of benzaldehyde with H2O2 using the title compound as catalyst was carried out in a liquid-solid system, showing that the compound had high oxidative catalytic activity to the reaction. 【总页数】5页(640-644)
