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

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-dimeth­oxy­phenyl­acetate (L) anions and two N atoms from a 1,10-phenanthroline (phen) mol­ecule. The L ligands are coordinated to the Ho(III) 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].
