Deskripsi
In the title compound, [Er(C18H22.5N2O4)2], the Er atom is located on a twofold rotation axis and is eight-coordinated by four O atoms and four N atoms from two symmetry-related 6,6′-dimethoxy-2,2′-(ethane-1,2-diyldiiminodimethylene)diphenolate(1.5−) ligands. Due to disorder of one phenolate H atom with half-occupation, the overall charge of one tetradentate ligand is −1.5. The ligand molecules are stabilised by intramolecular N—H...O and O—H...O hydrogen bonds and are linked into a chain parallel to the a axis by a C—H...O hydrogen bond. Neighbouring chains are connected by van der Waals forces, resulting in a three-dimensional network.
