The synthesis of zinc(II) complexes of 2-(2-mercaptophenyl)-iminophenol by electrochemical cleavage of a disulfide bond; the crystal structure of {(2, 2′-bipyridine)[2-(2-mercaptophenyl)iminophenoxy]}zinc(II)
The electrochemical oxidation of anodic zinc in an acetonitrile solution of the Schiff base derived from the required salicylaldehyde and bis-(2-aminophenyl)disulfide, L2H-2, yields compounds having the formulation ZnL. When 1,10-phenanthroline (phen) or 2,2'-bipyridine (bipy) is added to the electrolytic phase [ZnLphen] or [ZnLbipy] are obtained. The crystal structure of 2,2'-bipyridine[2-(2-mercaptophenyl)]iminophenoxy}zinc(II) [ZnL1bipy] has been determined. The compound crystallises in the triclinic space group Pl(No. 1) with two molecules in the unit cell and cell constants a = 6.526(2), b = 11.686(3), c = 13.346(4) angstrom; alpha = 107.72(2), beta = 92.08(2), gamma = 91.79(2)-degrees. The zinc atom has a distorted trigonal bipyramidal geometry. The IR and H-1 NMR spectra of complexes are discussed and related to the structure.
