    The mixed-ligand picolinato (pic) complex of Cu(II) with 4-methylimidazole (4-MeIm),[Cu(pic) 2 (4-MeIm) 2], was synthesized and characterized by elemental analysis, magnetic susceptibility, spectroscopic methods (UV/vis and FT-IR) and X-ray diffraction. In the slightly distorted octahedral cis-bis(4-methylimidazole)bis(picolinato)copper(II) complex, the pic ligands are coordinated to the Cu(II) ion as bidentate N,O-donors forming chelate rings. The 4-MeIm ligands are N-coordinated in cis positions. The complex crystallizes in the triclinic space group P?1 with unit cell parameters a=9.204(5), b=9.498(5),c=13.095(5)?A, ?=90.395(5), ?=101.687(5), ?=112.291(5)?andZ=2. ydrogen bondings and C-H···?interactions occur between picolinato and methylimidazoleligands of eighboring complex molecules. The thermal decomposition of the complex is described
