title: Tetra-kis(μ-3,4-dimeth-oxy-phenyl-acetato)-bis-[(3,4-dimeth-oxy-phenyl-acetato)(1,10-phenanthroline)holmium(III)].
abstract: In the centrosymmetric title compound, [Ho(2)(C(10)H(11)O(4))(6)(C(12)H(8)N(2))(2)], the Ho(III) atom is nine-coordinated by seven O atoms from the 3,4-dimeth-oxy-phenyl-acetate (L) anions and two N atoms from a 1,10-phenanthroline (phen) mol-ecule. The L ligands are coordinated to the Ho(III) ions in three modes: chelating, bridging and bridging-tridentate. Intra-molecular C-H⋯O inter-actions occur. The crystal packing is stabilized by inter-molecular C-H⋯O inter-actions and weak aromatic π-π inter-actions between phen mol-ecules and the aromatic rings of the L ligands [centroid-centroid distance = 3.821 (2) Å].
