摘要: ABSTRACT The rational synthesis and the structural magnetic characterization of a nickel cluster are presented. compound comprises rhomblike Ni4O16 group encapsulated between two-heptadentate tungstoarsenate ligands [AsW9O34]9−. crystal structure K10[Ni4(H2O)2(AsW9O34)2]·4H2O was solved in monoclinic, P21/n symmetry, with a=12.258(3) A, b=21.232(4) A, c=15.837(3) A, β=92.05(3)°, V=4119.1(14) A3, Z=2, R=0.0862. Ni(II) derivative compared that Cu(II), Zn(II), Co(II) Mn(II) derivatives. Ni4O14-(H2O)2 unit shows no Jahn-Teller distortion. On other hand, ferromagnetic exchange interactions within (J=7.8 cm−1, J′=13.7 cm−1) an S=4 ground state, highest spin state reported heteropoly complex. Its redox electrochemistry has been studied acid buffer solutions using cyclic voltammetry. It exhibited two steps one-electron waves attributed to process...
