Synthesis, Crystal Structure, and Luminescent Properties of a Cadmium(II) Coordination Polymer Constructed by Bis(4-(1H-Imidazol-1-yl)phenyl) Methanone and 1,4-Benzenedicarboxylate Ligands

A coordination polymer with the V -shaped ligands, {Cd 2 (bipmo) 2 ( bdc ) 2 ⋅H 2 O} n ( 1 ), (where bipmo is bis(4-(1 H -imidazol-1-yl)phenyl)methanone; H 2 bdc is 1,4-benzenedicarboxylic acid) has been prepared and structural characterized by IR, elemental analyses and single-crystal X-ray diffraction. X-ray diffraction analyses show that the Cd(II) ion is in a distorted octahedral environment, of which the donor atoms are provided by oxygen atoms of the bdc 2– ligands and nitrogen atoms of the bipmo ligands. From a topological point of view, the framework of 1 exhibits two-fold 3D uninodal six-connected interpenetrating framework with the (4 12 ⋅ 6 3 ) pcu topology.
