Abstract
A series of complexes of formula [M(II)(bpy)2(ArSO2-N-aminoacidato-NO)]·3H2O [bpy=2,2′-bipyridine, M(II)=Zn(II), ArSO2-N-aminoacidato-NO=N(toluene-p-sulfonyl)- and N(benzenesulfonyl)-glycinate-NO dianion, hereafter abbreviated as tsgly-NO and bsgly-NO, respectively, M(II)=Cd(II), ArSO2-N-aminoacidato-NO=tsgly-NO] was separated and investigated by spectroscopic and X-ray methods. The crystal structure of [Cd(bpy)2(tsgly-NO)]·3H2O was determined. The compound crystallizes in the monoclinic space groupP2/n,Z=4,a=15.427(4),b=13.580(2),c=15.546(4)Å, β=110.97(3),R=0.041,R w =0.043. The structure consists of monomeric, approximately octahedral [Cd(bpy)2(tsgly-NO)] units with a N5O donor atom set, which gives rise to three almost orthogonal five-membered chelate rings. The IR spectra suggest similar environments for all the complexes.
