Abstract
Abstract A series of compounds of N-p-tolylsulfonyl- l -glutamic acid with divalent Cu, Zn and Cd are synthesized and characterized. For the complexes [Zn(tsgluO)(H2O)2]·H2O (1), [Cd2(tsgluO)2(H2O)6] (2) and [Cd(bipy)(tsgluO)] (3) the crystal and molecular structure have been determined by X-ray diffraction (tsgluO=N-p-tolylsulfonyl- l -glutamate dianion, bipy=2,2′-bipyridine). In compound 1 the ZnII ion exhibits a tetrahedral geometry arising from coordination of two carboxylic oxygens of two amino acid molecules and of two water molecules. In compound 2 each CdII ion of the dimeric unit is coordinated by oxygen atoms of tsgluO2− and water molecules in a distorted octahedral environment. In compound 3 the CdII ion is coordinated by 2,2′-bipyridine nitrogens and four oxygen atoms from three different tsgluO2− in a distorted octahedral geometry.
