Abstract

A novel series of [(dpca)MX₂] (M = Cu, X = Cl; M = Cd, X = Br and M = Zn, X = NO₃) complexes were synthesized through the reaction of N,N-di(2-picolyl)cyclohexylamine (dpca) with the corresponding metal starting materials. X-ray crystallographic analysis determined that the metal center in complexes [(dpca)CuCl₂], [(dpca)CdBr₂] and [(dpca)Zn(NO₃)₂] showed a distorted 5-coordinated square pyramidal, trigonal bipyramidal, and 7-coordinated pentagonal bipyramidal geometry, respectively, involving coordination of the nitrogen atom of the cyclohexylamine moiety with the metal center. Specifically, the catalytic activity of [(dpca)Zn(NO₃)₂] (1.04 × 10⁵ g PMMA/mol Zn·h) for the polymerization of methyl methacrylate (MMA) in the presence of modified methylaluminoxane (MMAO) at 60 °C was six-fold higher than the reference complex [ZnCl₂] (1.73 × 10 ⁴ g PMMA/mol Zn·h).
