Carbonate, oxalato and malonato bridged Cu(II) and Co(II) complexes with an octaazamacrocyclic ligand
MetadataShow full item record
Four new Cu(II) and Co(II) complexes having an octaazamacrocyclic ligand derived from cyclam, N,N'N,",N'''-tetrakis(2-pyridylmethyl)-1,4,8,11-tetraazacyclotetradecane, with either an mu-carbonato, oxalato or malonato as the additional ligand were isolated and investigated by elemental analysis, electronic and IR spectroscopy, as well as molar conductivity, magnetic and cyclic voltammetry (CV) measurements. Their microbiological activity was also tested. Binuclear or tetranuclear structures, depending on the bridging ligand and metal ion, was proposed.
Keywords:Cu(II) acid Co(II) complexes / octaazamacrocycle / mu-carboxylato ligands
