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].
在中心对称的标题化合物[Ho₂(C₁₀H₁₁O₄)₆(C₁₂H₈N₂)₂]中,Ho(III)原子由来自3,4-二甲氧基苯乙酸(L)阴离子的七个O原子和来自一个1,10-菲咯啉(phen)分子的两个N原子九配位。L配体以三种模式与Ho(III)离子配位:螯合、桥连和桥连三齿。分子内存在C—H⋯O相互作用。晶体堆积通过分子间C—H⋯O相互作用以及phen分子与L配体的芳环之间的弱芳香π-π相互作用得以稳定[质心-质心距离 = 3.821 (2) Å]。
