  • Published:1991-04-25

Five new title compounds have been synthesized by the reaction of Cp3Ln (Cp = C5H5; Ln = Nd, Sm, Gd, Dy, Yb) with nitromethane in THF (tetrahydrofuran) at room temperature All the compounds were characterized by elemental anal., IR and MS spectra, indicating that they are monomers with carbonitronate groups bonded bidentately to metals by the oxygen atoms of nitro groups. Compounds of Nd and Sm are thermally unstable, which tend to disproportionate into a mixture of Cp3Nd (or Sm) and (CH2NO2)3Nd (or Sm) at above 120 癈.
