It crystallizes in monoclinic, space group P2l/c with unit cell parameters: a = 9.7085(7),b = 26.409(2), c = 14.014(1) ,?= 100.237(3), V = 3535.9(2) 3,Z = 4,C30H24Cl6Fe2N6NiO,Mr = 867.66, Dc = 1.630 g/cm3,F(000) = 1744, (MoK? = 1.824 mm-1, the final R = 0.0394 and wR = 0.0475 for 2750 observed reflections with I ≥ 2(I). The title compound contains cation of [Ni(bipy)3]2+ and anion of [(-oxo)Fe2Cl6] 2- which consists of two [FeCl3] fragments connected by an oxo bridge with the bond distances of Fe(2)O(1) 1.752(2) and Fe(1)O(1) 1.763(2) , and the bond angle of Fe(2)O(1)Fe(1) 148.6(2)? In the [Fe2(-oxo)Cl6]2- complex, the two iron(Ⅲ) centers exhibit a tetrahedral coordination with the distorted tetrahedron formed by three Cl atoms and one oxo bridge.展开更多
