The first S-bridged (CoCdCoIII)-Cd-III-Co-II and (CoCd2CoIII)-Cd-III-Co-II stuctures controlled by chirality of mono(thiolato)-type cobalt(III) units
Treatment of the racemic Delta/Lambda-[Co(aet)(cn)(2)](2+) (aet = 2-aminoethanethiolate) with Cd-II in the presence of excess Cl- in water gave Delta Lambda-[CdCl4{Co(aet)(en)(2)}(2)](2+) (Delta Lambda-[1](2+)), while the corresponding reaction using the optically active A[Co(aet)(en)2]2+ produced Lambda Lambda-[Cd2Cl7{Co(aet)(en)(2)}(2)](+) (Lambda Lambda-[2](+)). The crystal structures of these complexes were determined by X-ray crystallography.
