摘要：
The title ligand is obtained in two steps with high overall yield, and is soluble in aromatic solvents, making its liquid liquid extraction performance of potential interest. The ligand forms a stable 1: 1 coordination complex with Er(NO3)(3) and the molecular structure was determined by single crystal X-ray diffraction methods. The Er(III) ion is chelated by one tridentate ligand and three bidentate nitrate groups. The structural results are discussed in the context of complexes formed by related ligands.
