The copper(II) complexes CuLCl2 (1) and CuLBr2 (2), with the chelating pyrazolylpyrimidine ligand 4-(3,5-dimethyl-H-1-pyrazol-1-yl)-2-methyl-6-phenylpyrimidine (L), have been synthesized. A single crystal Xray diffraction study revealed that 1 and 2 have molecular mononuclear structures. The molecules of 1 and 2 form chains in the crystal structures of these compounds due to the formation of pi-pi-stacking interactions between the pyrimidine and the phenyl rings. The complexes, in combination with the co-catalyst methylaluminoxane (MAO), reveal catalytic activity in ethylene polymerization, while the free ligand L is inactive. (C) 2011 Elsevier Ltd.
