Popis:	Metal Complexes of Biologically Important Ligands. CLXVI Metal Complexes with Ferrocenylmethylcysteinate and 1,1′-Ferrocenylbis-(methylcysteinate) as Ligands A series of complexes of transition metal ions ( Cr3+, Mn2+, Co2+, Ni2+, Cu2+, Zn2+ ) and of lanthanide ions ( La3+, Nd3+, Gd3+, Dy3+, Lu3+ ) with the anions of ferrocenylmethyl-L-cysteine [(C5H5)Fe(C5H4CH(R)SCH2CH(NH3+)CO2−] (L1) and with the dianions of 1,1′-ferrocenylbis(methyl-L-cysteine) [Fe(C5H4CH(R)SCH2CH(NH3+) CO2−)2] (R = H, Me, Ph) (L2) as N,O,S-donors were prepared. With the monocysteine ferrocene derivative L1 as ligands complexes [MIIL12] or [CrIIIL12]Cl type complexes are formed whereas the bis(cysteine) ligand L2 yields insoluble complexes of type [ML2]n, presumably as coordination polymers. The magnetic moments of [MnIIL2]n, [PrIIIL2]n(OH)n and [DyIIIL2]n(OH)n exhibit “normal” paramagnetism.
