摘要：

A new reduced molybdenum(V) phosphate (H(3)dien)(2)(H(2)dien)(2)[NaMo12O24 (OH)(6) (H2PO4)(HPO4)(5)(PO4)(2)]center dot nH(2)O (n = 10.92, dien = diethylenetriamine) has been synthesized under hydrothermal conditions and characterized by elemental analyses, IR and X-ray diffraction. C16H96.84Mo12N12NaO72.92P8 (M-r = 3046.73) crystallizes in the monoclinic system, space group P2(1)/c with a = 13.3575(18), b = 21.907(3), c = 15.654(2) angstrom, beta = 110.22(2)degrees, V = 4298.4(10) angstrom(3), D-c = 2.354 g/cm(3), Z = 2, mu(MoK alpha) = 1.966 mm(-1), F(000) = 2,990.4, the final R = 0.0357 and wR = 0. 1086 for 8739 observed reflections with I > 2 sigma(I). It consists of sandwich-shaped cluster anions [Na{Mo6P4}(2)](10-) held together into a three-dimensional supramolecular framework through intermolecular hydrogen-bonding contacts. A probe reaction of the oxidation of acetaldehyde with H2O2 showed that this compound has high catalytic activity in the reaction.
