Cadmium(II) complexes containing 2,2′-dimethyl-4,4′-bithiazole ligand: Synthesis, characterization, and crystal structure

چکیده مقاله

Mononuclear and coordination polymer compounds of 2,2′-dimethyl-4,4′-bithiazole (dm4bt) ligand have been prepared by metallation of dm4bt with Cd(NO₃)₂ 4H₂O and CdCl₂ H₂O. The compounds were characterized by IR, ¹H NMR, UV-Vis spectroscopy, and X-ray crystallography. The structural study of [Cd(dm4bt)₂(NO₃)₂] H₂O (1) shows that the complex is a monomeric seven-coordinate (CdN₄O₃) cadmium(II)-bithiazole system with two bidentate dm4bt and mono and bidentate nitrates. The structure of [Cd(dm4bt)Cl₂]_n (2) is a distorted octahedral environment around the cadmium(II) (CdN₂Cl₄) forming a 1-D coordination polymer as a result of bridging by two chlorides and 2-D structure from π-π stacking interactions. © 2009 Taylor & Francis.
