A new 1D coordination polymer[Co(bpp)3Cl2(H2o)2]n 1(bpp = 1,3-bis(4-pyridyl)-propane)was synthesized and characterized by elemental analysis,IR spectrum and single-crystal X-ray diffraction.The crystal belongs to the orthorhombic system,space group Ibca with a=16.569(9),b = 17.240(10),c = 27.087(16)(A),V= 7738(8)(A)3,Z = 8,Dc = 1.306 g/cm3,Mr = 760.65,λ(MoKa)= 0.71073(A),μ = 0.623 mm-1,F(000)= 3192,the final R = 0.0678 and wR = 0.2011.The Co(Ⅱ)atom is coordinated in a slightly distorted octahedral CON4Cl2 geometry by two C1 atoms in the axial positions,four N atoms from the two bridging bpp ligands and two pendant bpp ligands.The CON4C12 octahedra are connected by the bridging bpp ligands to form a 1D neutral coordination polymer chain.The chains are linked by face-to-face π-π interactions between adjacent pendant bppligands to give rise to a 3D supramolecular architecture.The photoluminescent investigation indicates that the emission of 1 is attributed to ligand-centered emission.The variable-temperature magnetic susceptibility measurement shows weak antiferromagnetic behavior in the complex.
