Tris(1,10-phenanthroline-²N,N')cobalt(III) tris(trifluoromethanesulfonate) dihydrate

M. Hanauer, A. Neshat and T. P. Bigioni

Abstract: The title compound, [Co(C₁₂H₈N₂)₃](CF₃SO₃)₃·2H₂O, crystallizes to form infinite chains of complex cations that are connected through offset face-to-face and edge-to-face interactions between their phenanthroline ligands. The chains are themselves interconnected through weak offset face-to-face ligand interactions. The three trifluoromethanesulfonate anions of the asymmetric unit are connected with one another through the two water molecules by hydrogen bonds. One of the trifluoromethanesulfonate anions is described by a disorder over three positions, with occupancies of 0.35, 0.35 and 0.3 in the refined model.

Formula: [Co(C₁₂H₈N₂)₃](CF₃O₃S)₃·2H₂O
