Abstract: Six new solid complexes of the light lanthanide picrate with 18-crown-6 ether have beensynthesized in ethanol solution.The complexes are formularized to be RE(Pic)3·18C6·H2O,(RE = La, Pr, Nd, Sm, Eu, and Gd, Pic = picrate).The compositions and structures of thecomplexes have been characterized by elemental analyses, molar conductance measurements,IR spectra, 1H-NMR spectra and X-ray powder diffractometry.

Key words: 18-crown-6 ether, picrate, light lanthanide, complex, synthesis
