中文摘要	the rational synthesis and the structural and magnetic characterization of a nickel cluster are presented. the compound comprises a rhomblike ni4o16 group encapsulated between two-heptadentate tungstoarsenate ligands [asw9o34](9-). the crystal structure of k-10[ni-4(h2o)(2)(asw9o34)(2)](.)4h(2)o was solved in monoclinic, p2(1)/n symmetry, with a = 12.258(3) angstrom, b = 21.232(4) angstrom, c = 15.837(3) angstrom, beta = 92.05(3)degrees, v = 4119.1(14) angstrom(3), z = 2, and r = 0.0862. the crystal structure of the ni(ii) derivative was compared with that of the cu(ii), zn(ii), co(ii) and mn(ii) derivatives. the ni4o14(h2o)(2) unit in the compound shows no jahn-teller distortion. on the other hand, the ni(ii) derivative shows ferromagnetic exchange interactions within the ni4o16 group (j = 7.8 cm(-1), j' = 13.7 cm(-1)) and an s = 4 ground state, the highest spin state reported in a heteropoly complex. its redox electrochemistry has been studied in acid buffer solutions using cyclic voltammetry. it exhibited two steps of one-electron redox waves attributed to redox processes of the tungsten-oxo framework. the new catalyst showed an electrocatalytic effect on the reduction of no2-.
