Abstract
  • Lanthanide(III) complexes with composition Ln(nic)(H2O)n(pic)3(nic) (Ln = Pr , Nd n=8; Tm n=7) (pic = picrate, nic =nicotinamideN-O) were obtained by reaction of the hydrated lanthanide picrate with nicotinamideN-oxide in ethanol. They were characterized by elemental analysis and IR spectra. The molecular structures of Pr , Nd and Tm complexes were established by X-ray crystallography. Different triclinic phases have been detected for the isostructural Nd and Pr derivatives. They are 9 coordinated to eight water molecules and a monodentate nic ligand while the apparently isomorphous Tm derivative looses a water molecule with a 8 coordination number and a coordination geometry changing from tricapped trigonal prism (Pr,Nd) to square antiprismatic.
