摘　　要：A new compound, \[Ni(en)\-3\]\-2\[Ni(en)\-2(H\-2O)\-2\]\[As\-6V\-\{15\}O\-\{42\}\]·4H\-2O, was first prepared by hydrothermal synthesis and characterized by elemental analysis, IR, TGA\|DSC, ESR and single crystal X\|ray diffraction. Crystal data: monoclinic, space group \%C\-c, a\%=1\^523 6(3) nm, \%b\%=2\^051 8(4) nm, \%c\%=2\^395 9(5) nm, \%β=97\^41(3)°, V\%=7\^427(3) nm\+3, \%Z=4, R=0\^057 0, wR\-2=0\^135 7\%. The polyanion consists of six AsO\-3 pyramids and fifteen VO\-5 pyramids. Counterions are complex ions with octahedral structure, which consist of NH\-2CH\-2CH\-2NH\-2 and Ni\+\{2+\}.A new compound, \[Ni(en)\-3\]\-2\[Ni(en)\-2(H\-2O)\-2\]\[As\-6V\-\{15\}O\-\{42\}\]·4H\-2O, was first prepared by hydrothermal synthesis and characterized by elemental analysis, IR, TGA\|DSC, ESR and single crystal X\|ray diffraction.
