Synthesis, properties and X-ray structure for the mononuclear complex of [{(1-methyl imidazol-2-yl)methylene}-2-aminoethylpyridine]-dichloro copper (II) monohydrate

The crystal structure of the title complex, [CuCl2(C12H14N4)(H2O)], is composed of discrete molecules. The Cu(II) atom is coordinated by two chloride ligands and three nitrogen atoms from the ligand in a distorted tetragonal pyramidal coordination environment with Cu-N distances of 2.053(2), 2.0023(2) and 2,035(2) Angstrom. Cu-Cl distances of 2.538(1) Angstrom and 2.302(1) Angstrom and N-Cu-N of 90.97(0.07), 167.16(0.07) and 80,32(0.07)degrees and Cl-Cu-Cl angles of 106.90 (0.003)degrees. (C) 2002 Elsevier Science Ltd.
