Tetrakis(μ-3,4-dimethoxyphenylacetato)bis[(3,4-dimethoxyphenylacetato)(1,10-phenanthroline)holmium(III)]

Abstract

In the centrosymmetric title compound, [Ho2(C10H11O4)6(C12H8N2)2], the HoIII atom is nine-coordinated by seven O atoms from the 3,4-dimethoxyphenylacetate (L) anions and two N atoms from a 1,10-phenanthroline (phen) molecule. The L ligands are coordinated to the HoIII ions in three modes: chelating, bridging and bridging–tridentate. Intramolecular C—H...O interactions occur. The crystal packing is stabilized by intermolecular C—H...O interactions and weak aromatic π–π interactions between phen molecules and the aromatic rings of the L ligands [centroid–centroid distance = 3.821 (2) Å].
