Abstract
The asymmetric unit of the title iron hybrid fluoride, (C(3)H(12)N(2))(2)[FeF(6)]F center dot 3H(2)O, contains two propane-1,3-diaminium [(H(2)dap)(2+)] cations, an octahedral [FeF(6)](3-) anion, an isolated F(-) anion and three water molecules of solvation. Each [ FeF(6)](3-) anion is surrounded by four separate hydrogen-bonded water molecules in the equatorial sites and by five separate aminium cation donor groups. The axial F atoms are only involved in N-H center dot center dot center dot F hydrogen bonds, resulting in a three-dimensional structure.
