Crystal data for 1: monoclinic, space group C2/c with a = 12.824(3), b = 27.873(6), c = 21.092(4) , b = 92.93(3), V = 7529(3) 3, Z = 4, Dc = 2.012 g/cm3, Mr = 2280.56, F(000) = 4476 and m = 3.092 mm-1. The final R and wR are 0.0769 and 0.1783, respectively for 4203 observed reflections with I>2s(I). The structure consists of [V18O42(Cl)]7- clusters linked by trans- {Ni(en)2} groups into linear chains, while cis-{Ni(en)2} groups provide the cross-linking adjacent chains to form a two-dimensional structure.展开更多
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.展开更多
