Bis(propane-1,3-diaminium) hexafluoridoferrate(III) fluoride trihydrate

Abstract

The asymmetric unit of the title iron hybrid fluoride, (C3H12N2)2[FeF6]F·3H2O, contains two propane-1,3-diaminium [(H2dap)2+] cations, an octahedral [FeF6]3− anion, an isolated F− anion and three water molecules of solvation. Each [FeF6]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...F hydrogen bonds, resulting in a three-dimensional structure.
