Abstract: In the title compound, fac-[Cr(tpa)(H₂O)₃](CF₃SO₃)₃ [tpa is tris(2-pyridyl)amine; C₁₅H₁₂N₄], the Cr^III ion is coordinated by the symmetry-related N atoms of tpa, which acts as a tripodal ligand, and O atoms of water; a threefold rotation axis passes through the Cr and amine N atoms, with Cr-N_pyridyl and Cr-O distances of 2.0403 (12) and 1.9815 (11) Å, respectively. A three-dimensional network is formed by intermolecular O-HO hydrogen bonds between coordinated water molecules and sulfonate groups of the anions.
