| Abstract: A novel one-dimensional cadmium(Ⅱ) complex {[Cd(BDC)(bpimb)0.5(H2O)]·H2O}n(1) with phthalic acid (H2BDC) and 1,4-bis((2-(pyridin-2-yl)-1H-imidazol-1-yl)methyl)benzene (bpimb) has been synthesized by means of hydrothermal method and characterized by elemental analysis, IR spectrum, thermal analysis and single-crystal X-ray diffraction. The crystal is of monoclinic, space group P21/c with a=1.591 9(3) nm, b=0.689 23(14) nm, c=2.229 5(3) nm, β=126.882(10)°, V=1.956 6(6) nm3, Dc=1.727 g·cm-3, Z=4, F(000)=1 020, Goof=1.070, R1=0.049 4, wR2=0.101 9. Complex 1 shows a novel one-dimensional (1D) ribbon structure and further extended into a 3D supramolecular structure through O-H…O and C-H…O hydrogen bonding interactions. Luminescent studies show that complex 1 exhibits intense blue fluorescent emission. CCDC: 768901. |
