Abstract
The title compound, [Ho2(C9H9O3)6(C12H8N2)2], lies about a centre of symmetry and is comprised of six 2-phenoxypropionate (POPA) anions and two 1,10-phenanthroline (phen) ligands. The two HoIII ions are linked by four POPA groups utilizing both bi- and tridentate bridging modes to form an inversion-symmetric dimer. Each HoIII ion is nine-coordinate, with a chelating 1,10-phenanthroline molecule, one bidentate chelating carboxylate group, two bidentate bridging carboxylate groups and two tridentate bridging carboxylate groups in a distorted mono-capped square antiprism geometry. There are weak π–π aromatic interactions between the phen groups and aromatic rings of the POPA ligands [centroid–centroid distance = 3.829 (1) Å].
