Coordination complexes based on 4-aminobenzonitrile with different dimensionalities

Abstract

Reaction of 4-aminobenzonitrile with different transition metal ions in the presence of chloride provides metal complexes of different dimensionalities Whereas platinum forms a 0-D mononuclear complex {[PtCl2(4-ABN) 2} 1, three new coordination polymers {[Zn(4-ABN)2(H 2O)2](ClO4)2}n 2, {[Cu(4-ABN)2(MeOH)2](ClO4)2} n 3, and {Cd(4-ABN)Cl2}n 4 have been synthesized and characterized.Complexes 2 and 3 crystallize in 1-D polymeric chains, whereas 4 forms a 3-D coordination network, based on fused 12-membered rings of cadmium and chloride A topological analysis of 4 reveals a uninodal five-connected network with the point (Schlafli) symbol of (44 × 66) and the nov (5/4/08) topology All the isolated complexes were characterized by IR, elemental, and X-ray single crystal structural analyses Complexes 1, 2, and 4 were additionally characterized by NMR spectroscopy © 2013 Taylor & Francis.
