Abstract

In the title compound, [Ho(NO3)3(C12H8N2)2], the ten-coordinate HoIII ion is chelated by four N atoms from two phenanthroline (phen) ligands and six O atoms from three bidentate nitrate groups. The environment around the Ho atom can be described as a distorted bicapped square antiprism. Two phenanthroline ligands form a dihedral angle of 43.72 (13)°. Short intermolecular distances between the centroids of the six-membered rings [3.6887 (14)–3.8374 (16) Å] indicate the existence of π–π interactions, which link the molecules into stacks extended in the [10] direction. The crystal packing is further stabilized by weak intermolecular C—H⋯O hydrogen bonds.
