Abstract

A series of late transition metal complexes, [(bpma)Co(μ–Cl)Cl] ₂ , [(bpma)Cu(μ–Cl)Cl] ₂ , [(bpma)Zn(μ–Cl)Cl] ₂ and [(bpma)Cd(μ–Br)Br] ₂ (where bpma is 4-bromo-N-((pyridin-2-yl)methylene)benzenamine) have been synthesized and structurally characterized. The X-ray structures of dimeric complexes [(bpma)M(μ–X)X] ₂ (M = Co, Cu and Zn, X = Cl; M = Cd, X = Br) showed a distorted 5-coordinate trigonal bipyramidal geometry involving two nitrogen atoms of N,N-bidentate ligand, two bridged and one terminal halogen atoms. The complex [(bpma)Cu(μ–Cl)Cl] ₂ revealed the highest catalytic activity for the polymerisation of methyl methacrylate in the presence of modified methylaluminoxane with an activity of 9.14 × 10 ⁴ g PMMA/mol·Cu·h at 60 °C and afforded syndiotactic poly (methylmethacrylate) (rr = 0.69).
