In the title compound, [Ho(NO3)3(C12H16N3O2)2], the HoIII ion is ten-coordinated in a distorted bicapped square-antiprismatic environment by two N,O-bidentate nitronyl nitroxide radical ligands and three O,O′-bidentate nitrate anions. Complex molecules are connected by C—H⋯O hydrogen bonds into a three-dimensional network.
