Synthesis and Crystal Structure of a New Coordination Polymer from Cadmium and V-Shape Ligand Bis(imidazol-1-yl) methane

Abstract  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) ?, b = 9.3894(18) ?, c = 8.6926(17) ?, β = 123.499(2)°, V = 980.1(3) ?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.
