Abstract

The reaction between [CuCl₂ · 2H₂O] and N,N0-bidentate N-(pyridin-2-ylmethyl)aniline (L_a) and its derivatives (L_b and L_c) in methanol yielded new Cu(II) complexes; namely polynuclear [CuL_aCl₂]_n, dinuclear [CuL_b(μ-Cl)Cl]₂, and mononuclear [CuL_cCl₂], respectively. Monomeric [CuL_cCl₂] showed a distorted square planar geometry around copper metal-based on X-ray crystallography. The polymeric [CuL_aCl₂]_n and dimeric [CuL_b(μ-Cl)Cl]₂ had a chloro-bridged five-coordinated and a distorted square pyramidal geometry around the Cu(II) center. The Cu⋯Cu′ distance was 3.915(1) Å in [CuL_aCl₂]_n and 3.928(1) Å in [CuL_b(μ-Cl)Cl]₂. Interestingly, magnetic susceptibility (χ) measurements of complexes [CuL_aCl₂]_n and [CuL_b(μ-Cl)Cl]₂ exhibited a weak antiferromagnetic interaction.
