Hydrothermal synthesis, crystal structure and photoluminescence of a novel one-dimensional cadmium(II) complex: {[Cd(BDC)(bpimb)_0.5(H ₂O)] · H₂O}_n

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)-lH-imidazol-l-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, 6=0.689 23(14) nm, c = 2.2295(3) nm, β=126.882(10)°, V=1.9566(6) nm³, D_c =1.121 g · cm³, 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 0-H· · · O and C-H··· O hydrogen bonding interactions. Luminescent studies show that complex 1 exhibits intense blue fluorescent emission.
