Synthesis and Crystal Structure of{[Mn(H2O)4(3, 3′-azpy)](3, 3′-azpy)3(PF6)2}n

The complex {[Mn(H2O)4(3, 3?-azpy)](3, 3?-azpy)3(PF6)2}n (3, 3?-azpy = 3, 3?- azobispyridine) has been synthesized and characterized. The crystal (C40H40F12MnN16O4P2, Mr = 1153.76) belongs to the triclinic system, space group P ī with the following crystallographic parameters: a = 10.761(2), b = 11.040(2), c = 23.365(4) ?, ( = 85.52(1), ( = 82.69(1), ( = 70.44(1)°, V = 2592.5(8) ?3, Dc = 1.478 g/cm3, ((MoK() = 4.16 cm-1, F(000) = 1174, Z = 2, final R = 0.0493 and wR = 0.1158 for the observed reflections (I > 2.00((I)). The X-ray analysis revealed that manganese(Ⅱ) cation coordination environment is a distorted octahedral geometry, and the Mn2+ cation is coordinated by four oxygen atoms of water in the equatorial plane, while the two nitrogen atoms of 3, 3?-azpy occupy the axial positions. The complex forms a one-dimensional chain structure via 3, 3?-azpy bridging ligand.
