| Popis: | The synthesis of 14 mixed-ligand solid complexes of lanthanide ions with 1,4-bis-(1′-phenyl-3′-methyl-5′-pyrazolone-4′)-1,4-butanedione (BPMPBD) and 1,10-phenanthroline (PHEN) in an alcohol—water solution is presented. The comosition of the complexes is determined as Ln 2 L 3 P 2 · n H 2 O (Ln = Y, La, Pr, Sm—Lu; L = BPMPBD; P = PHEN; n = 4,5) by chemical and elemental analyses. The complexes are regarded as binuclear and characterized by IR, UV, 1 H NMR, fluorescence spectra, thermoanalysis and conductance methods. |
