Acta Crystallogr Sect E Struct Rep Online. 2010 May 22;66(Pt 6):m702-3. doi: 10.1107/S1600536810018039.The asymmetric unit of the title iron hybrid fluoride, (C(3)H(12)N(2))(2)[FeF(6)]F·3H(2)O, contains two propane-1,3-diamin-ium [(H(2)dap)(2+)] cations, an octa-hedral [FeF(6)](3-) anion, an isolated F(-) anion and three water mol-ecules of solvation. Each [FeF(6)](3-) anion is surrounded by four separate hydrogen-bonded water mol-ecules in the equatorial sites and by five separate aminium cation donor groups. The axial F atoms are only involved in N-H⋯F hydrogen bonds, resulting in a three-dimensional structure.
