A 2D coordination polymer of [Cd(mbix)(BIPA)] (1) (H2BIPA=5-bromoisophthalic acid and mbix=1,3-bis(imidazol-1-ylmethyl) benzene) has been hydrothermal prepared and characterized by elemental analysis,IR spectroscopy and single-crystal X-ray diffraction structure analysis. The crystal is of monoclinic,space group P21/n with a=1.002 0(4) nm,b=1.754 4(7) nm,c=1.208 8(5) nm,β=94.271(5),V=2.119 1(15) nm3,Dc=1.861 g.cm-3,Z= 4,F(000)=1 168,Goof=1.085,R1=0.045 0,wR2=0.093 1. The crystal structure shows that the Cd2 units are formed by the two caroboxylate group adopting tridentate-chelating-bridging coordination mode,which are linked to form a 2D layer structure by the ligands,and further extended into a 3D supramolecular structure through C-H …O hydrogen bonding interactions and π-π weak interactions. In addition,complex 1 exhibits strong photolumine-scent emission at room temperature. CCDC:710801.
