The compleo (H 2 O) 4 (3,3’-azpy)(3,3’-azpy) 3 (PF 6 )2 n (3,3’-azpy =3,3’-azobispyridine)has been synthesized and characterized.The crystal(C 40 H 40 F 12 CoN 16 O 4 P 2 ,M r =1157.75)belongs to the triclinic system,space groupP1with the following crystallographi c 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 ,D c =1.502g·cm -3 ,μ(Mo Kα)=0.498mm -1 ,F(000)=1178,Z =2,and final R 1 =0.0469,w R 2 =0.1053for observed reflections 5549(I>2.00σ(I)).The X-ray analysis reveals that cob alt?cation coordination environment is a distorted octahedral geometry,the Co 2+ ion is coordinated by four oxygen ato ms of water in the equatorial plane,while the two nitrogen atoms of 3,3’-azpy occupy the axial positions.The complex forms a one-di mensional chain structure via3,3’-azpy bridging ligand.The one-dimension al chain forms three-dimensional network by hydrogen bonds andπ-πinter-actions.
