Lanthanum(III), praseodymium(III), neodymium(III), samarium(III), gado
linium(III), terbium(III) and dysprosium(III) chelates of the type [M(
RCOO)3].2H2O with the ligands 1-naphthoxy-, 2-naphthoxy- and 8-quinoli
nyloxyacetic acids have been isolated and characterized on the basis o
f elemental analyses, spectral, magnetic and thermal data. The IR data
show that the bonding of the carboxylato group to the metal ion is bi
dentate. A coordination number of six is suggested for the rare earth
metal ions in these complexes.
