【 摘 要 】

The crystal structure of the title complex, [Fe(C12H8N2)3][(CF3SO2)2N]2·H2O, is constructed by one octa­hedral [Fe(phen)3]2+ (phen = 1,10-phenanthroline) cation (point group symmetry 2), two Tf2N− [bis­(tri­fluoromethyl­sulfon­yl)imide] anions, and one water mol­ecule of crystallization (point group 2). The Fe—N bond lengths are indicative of a d6 low-spin state for the FeII ion in the complex. The dihedral angle between the phen ligands in the cation is 87.64 (6)°. The Tf2N− counter-anion is non-coordinating, with the –CF3 groups arranged in a trans fashion with respect to each other, leading to an anti,anti conformation of the –CF3 groups and –SO2N– moieties relative to the S—C bonds. The water mol­ecule of crystallization connects two O atoms of the Tf2N− anions through weak hydrogen bonds. C—H⋯O hydrogen-bonding inter­actions are also observed, consolidating the packing of the mol­ecules into a three-dimensional network structure.
