Synthesis and structure of novel mixed-metal complexes containing the heteronuclear ions [MIII{(OH)2Cr(NH3)4}4]7+ and [MIII{(OH)2Co(NH3)4}4]7+
Abstract
The synthesis and structural and magnetic properties of new pentanuclear complex ions containing a central tervalent metal ion [CeIII, YIII, LaIII, PrIII, or GdIII] co-ordinated to eight hydroxo groups which act as bridging ligands to four tervalent metal ions [CrIII or CoIII], are described.
