A Zinc(II) Coordination Polymer with Tetraiodoterephthalate: Synthesis, Crystal Structure, and Luminescence

A new coordination polymer {[Zn(BDC-I )- (DMSO) ]·(DMSO) (H O) (1) was prepared from the reaction of Zn(II) nitrate with 2,3,5,6-tetraiodo-1,4- benzenedicarboxylic acid (H BDC-I ) in DMSO=water and characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. Complex 1crystallizes in the orthorhombic space group Pnma and shows a zigzag chain coordination structure, which is assembled into a 2D network through weak C-H···O and C-H···π interactions. The thermal and photoluminescence properties of complex 1in the solid state are also reported
