【Abstract】 A new isopolyoxovanadate [Ni(1,10′-phen) 3] 2 [V Ⅳ 2V Ⅴ 8O 26] 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) nm 3, Z=4, R=0.040 3, wR 2=0.044 6. The compound exhibits an unusual empty ellipsoidal cage, which is constructed by eight {V ⅤO 4} tetrahedra and two {V ⅣO 5} square pyramids via corner-sharing modes. The chiral [Ni(1,10′-phen) 3] 2+ complexes act as the counter cations.更多还原
