ELECTROCHEMICAL SYNTHESIS AND CRYSTAL-STRUCTURES OF 2-PYRIDIN-2-YL-ETHYL)BENZENESULFONAMIDE)COPPER(II) AND BIS 2-PYRIDIN-2-YL-ETHYL)BENZENESULFONAMIDE)NICKEL(II)

The complexes [ML(2)] (M = Cu and Ni) were prepared by electrochemical oxidation of the appropriate metal in a solution of 2-(2-pyridyl)-N-t osylethylamine in acetonitrile. The crystal and molecular structures o f bis 2-pyridin-2-yl-ethyl)benzenesulfonamide}copper(II) and methyl-N- (2-pyridin-2-yl-ethyl)benzenesulfonamide} nickel(II) were determined b y X-ray diffraction. Both compounds are isotypical and crystallize in the triclinic space group P1 with one molecule in the unit cell. In bo th structures the metal atoms are in a distorted square-planar environ ment defined by two amide and two pyridyl nitrogen atoms. (C) 1997 Els evier Science Ltd.
