Synthesis, characterization and thermal properties of two novel lanthanide 2, 2'-biquinoline-4, 4'-dicarboxylate complexes

Two new lanthanide coordination complexes with 2,2'-biquinoline-4,4'- dicarboxylic acid (H2bqda) and 1,10-phenanthroline (phen), [La 2(Hbqda) 2 (bqda) 2 (phen)] n [1] and [Gd(bqda) 1.5 (phen)] n [2] were successfully synthesized and characterized. The complexes were obtained through hydrot...
