| Abstract: A coordination complex of [Cu(bpb)0.5(CH3COO)2]n (bpb=1,4-bis(pyridine-3-aminomethyl)benzene) has been synthesized and characterized by elemental analysis, IR spectra, TG and X-ray single crystal diffraction. The title complex crystallizes in triclinic with space group P1, a=0.771 98(15) nm, b=0.827 62(17) nm, c=1.116 0(2) nm, α=96.71(3)°, β=90.03(3)°, γ=105.39(3)°, and V=0.682 4(3) nm3, Z=2, R=0.042 4, wR=0.091 1. The title complex is composed of dicopper tetracarboxylate units. Copper(Ⅱ) atom asumes a square-pyramidal coordination geometry formed with one pyridyl N atom from bpb and four O atoms from four bridging acetate anions. Two adjacent dicopper tetracarboxylate units are linked into a 1D chain by the bpb ligands, which were further connected by inter-chain hydrogen bonds to form a 2D network structure. CCDC: 667605. |
