Abstract: The title compound, [Mn(C₇F₅O₂)(NO₃)(C₁₂H₈N₂)₂]₂·[Mn(NO₃)₂(C₁₂H₈N₂)₂], contains two types of molecules: [Mn(phen)₂(F₅C₆COO)(NO₃)] (A) and [Mn(phen)₂(NO₃)₂] (B) (phen = 1,10-phenanthroline) in a 2:1 ratio. Molecule B possesses a crystallographically imposed twofold rotation axis. The Mn ions in each of the two molecules are coordinated by four N atoms and two O atoms in a distorted octahedral geometry. The crystal packing exhibits interactions with relatively short distances of 3.6775 (14) and 3.8214 (13) Å between the centroids of six-membered rings from neighbouring molecules, and weak intermolecular C-HO and C-HF hydrogen bonds.
