'synthesis of novel biologically active mixed ligand yttrium(iii) complexes'

摘要

Present invention reports synthesis of biologically active mixed ligand Yttrium(III) complexes from Yttrium(III) chloride, 8-hydroxyquinoline (HQ) and N and / or O donor amino acids (HL) such as L-threonine, L-proline, L-hydroxyproline, L-isoleucine and L-serine. The method comprises conversion of Yttrium(III) chloride precursors to desired complexes using 8-hydroxyquinoline (HQ) as primary ligand (HQ) and amino acids (HL) as secondary ligands (HL) in 1:2:1 proportion. The synthesized mixed ligand Yttrium(III) complexes are novel as they are reported first time. The prepared complexes show excellent biological and germination activity.
