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
