Synthesis and crystal structure of a new coordination polymer from cadmium and v-shape ligand bis(imidazol-1-yl) methane

摘要

The new coordination polymer, [Cd(BIM)(2)(NO3)(2)](n), has been prepared from the reaction of bis(imidazol-1-yl) methane (BIM) with Cd(NO3)(2) in methanol and water. The compound were characterized by single crystal X-ray diffraction and IR spectroscopy, it crystallizes in the monoclinic space group C2/m with a = 14.400(3) angstrom, b = 9.3894(18) angstrom, c = 8.6926(17) angstrom, beta = 123.499(2)degrees, V = 980.1(3) angstrom(3), Z = 2. The Cd atoms are coordinated to four nitrogen atoms from four different BIM ligands and two nitrates to form a slightly distorted octahedral geometry. Further, the BIM ligands act as a bridged ligand to form 1D infinite cationic double chain with a 16-membered macrometallacyclic tetragonal box structure.
