. On coordination, deprotonation occurred and as a result, hap acted as a monobasic bidentate ligand. A coordination number 6 was assigned to the lanthanide(III) ions in these complexes with orthorhombic structure. All the complexes were thermally stable~150℃ and underwent decomposition in three stages with the formation of Ln2O3 as the final residues. Key words:synthesis; lanthanide(III......
