چکیده
The crystal structure of the title complex, [Fe(C12H8N2)3][(CF3SO2)2N]2·H2O, is constructed by one octa-hedral [Fe(phen)3](2+) (phen = 1,10-phenanthroline) cation (point group symmetry 2), two Tf2N(-) [bis-(tri-fluoromethyl-sulfon-yl)imide] anions, and one water mol-ecule of crystallization (point group 2). The Fe-N bond lengths are indicative of a d (6) low-spin state for the Fe(II) 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 mol-ecule of crystallization connects two O atoms of the Tf2N(-) anions through weak hydrogen bonds. C-H⋯O hydrogen-bonding inter-actions are also observed, consolidating the packing of the mol-ecules into a three-dimensional network structure.

The title hydrated complex, [Cu2(C7H4O3)(C12H8N2)4](C7H5O3)2·7.5H2O, is composed of dinuclear CuII complex cations, noncoordinating 4-hy-droxy-benzoate anions and water mol-ecules of crystallization. In the dinuclear complex cation, the CuII ions are bridged by a 4-oxidobenzoate ligand and thus each metal ion is five-coordinated by two chelating 1,10-phenanthroline (phen) mol-ecules and one ani...
