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), [Cd-2(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 Zn-II 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 Cd-II ion of the dimeric unit is coordinated by oxygen atoms of tsgluO(2-) and water molecules in a distorted octahedral environment. In compound 3 the Cd-II ion is coordinated by 2,2'-bipyridine nitrogens and four oxygen atoms from three different tsgluO(2-) in a distorted octahedral geometry. (C) 1999 Elsevier Science Ltd.
