CRYSTAL STRUCTURES AND LUMINESCENCE PROPERTIES OF A ONE-DIMENSIONAL CADMIUM COORDINATION POLYMER DERIVED FROM A FLEXIBLE BIS(IMIDAZOLE) LIGAND

A new Cd(II) coordination polymer, namely [Cd(pbmb)(mip)]n (pbmb = 1,1!-(1,3-propane)bis- (2-methylbenzimidazole), H2mip = 5-methylisophthalic acid), is hydrothermally synthesized and characterized by elemental analyses, infrared spectroscopy and single crystal X-ray diffraction analyses. It crystallizes in the triclinic space group P1 , a = 0.2883(11), b = = 11.3409(12), c = 13.2519(14) Е, ! = 69.6950(10)!, ! = 73.5850(10)!, ! = 63.8100(10)!, V = = 1285.8(2) Е3, Z = 2, C28H28CdN4O5, Mr = 612.94, Dc = 1.583 g/cm3, ! = 0.896 mm–1. In the complex, adjacent dinuclear units [Cd2(pbmb)2] are bridged by mip2– ligands in the !2-!2, !1 coordination modes to construct 1D ladder-like chains which are additionally assembled into a 2D supramolecular network via C—Hᄷ interactions. Moreover, the luminescence properties of the complex are described.
