Abstract
A novel ligand, acetylferrocene pyridine-2,6-diformylhydrazone (L), and its thirteen kinds of dinuclear yttrium and lanthanide (III) picrate complexes having the stoichiometric formula Ln 2L 2Pic 6· n( i-C 3H 7OH)· mH 2O (Pic = picrate anion; Ln = Y, La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, n = 2, m = 4; Ln = Er, Tm, Yb, n = 0, m = 2) have been synthesized and characterized by EA, IR, UV, 1H NMR and molar conductance. It was found that the ligand coordinates with the lanthanide picrates in the keto form and all the complexes prepared are 1:6 electrolytes in methanol.
