Abstract: A new isopolyoxovanadate [Ni(1,10′-phen)3]2 [VⅣ2VⅤ8O26] was hydrothermally synthesized and structurally characterized by the single crystal X-ray diffraction. The compound crystallizes in orthorhombic system, space group Pbcn with a=1.362 9(3) nm, b=2.215 6(4) nm, c= 2.571 2(4) nm, V=7.764(2) nm3, Z=4, R=0.040 3, wR2=0.044 6. The compound exhibits an unusual empty ellipsoidal cage, which is constructed by eight {VⅤO4} tetrahedra and two {VⅣO5} square pyramids via corner-sharing modes. The chiral [Ni(1,10′-phen) 3]2+ complexes act as the counter cations.
