| Abstract: The complex {[Co(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 (C40H40F12CoN16O4P2, Mr=1157.75) belongs to the triclinic system, space group P1 with the following crystallographic parameters: a=10.759(2),b=11.012(2), c=23.207(4)?; α=85.330(10), β=83.470(10),γ=69.770(10)°;V=2560.6(8)?3,Dc=1.502g·cm-3, μ(MoKα)= 0.498mm-1,F(000)=1178,Z=2, and final R1=0.0469, wR2=0.1053 for observed reflections 5549 (I> 2.00σ(I)).The X-ray analysis reveals that cobalt(Ⅱ) cation coordination environment is a distorted octahedral geometry, the Co2+ ion 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. The one-dimensional chain forms three-dimensional network by hydrogen bonds and π-π inter-actions. |
