| Mehrkernkomplexe von Zink und Cadmium mit ds-[C r(O H)2(en)2]+-Liganden H eterom etallic Polynuclear Com plexes of Zinc and Cadm ium with c/s-[C r(O H)2 (en)2]+ Ligands Frank R om inger, U lf Thew alt* A series of polynuclear heterometallic complexes containing chromium and zinc or cadmium were prepared by the reaction of c/s-[CrCl2(en)2]Cl and a zinc or cadmium salt in water and the molecular and crystal structures of 1 to 5 determined by X-ray structure analyses. The products contain chelating or bridging c7s-[Cr(OH)2(en)2]+ groups. For the zinc complexes a tetrahedral coordination is observed, and the [Cr(OH)2(en)2]+ units are found to act as bridges. |[Z nC l2(//-0H)C r(en)2(/u-0H)]C104]" (1) has a chain polymeric structure. [{ZnCl2(y'/-OH)Cr(en)2(//-0 H)} 2]C12 (2) has a cyclic structure. In the case of the cadmium complexes the [Cr(OH)2(en)2]+ units act as chelating ligands.
