The title compound was prepared at room temperature. Firstly, CdI2 (0.0366 g, 0.1 mmol) and phen (0.018 g, 0.1 mmol) were slowly added to 5 ml DMF and stirred for 30 min. Meanwhile, CuI (0.0191 g, 0.1 mmol) was added to another 5 ml of DMF, followed by slow addition of KI (0.0116 g,0.1 mmol) in 10 ml DMF until the solution became clear, and stirred for 30 min. Then the two solutions were mixed, stirred for 20 min, and filtered. After the solvent was slowly evaporated at -5°C, dark-purple crystals of the title compound weres obtained.
Considerable attention has been paid to heteronuclear metal complexes. At present, a variety of mixed metal complexes have been reported. (Chesnut et al., 1999. Ferbinteanu et al., 1998. Shiren et al., 2002.). Here, a new mixed metal complex is obtained under low temperature conditions. The asymmetric unit of the title compound, (I), contains one [CuI(phen)2]+ cation and a CdI2 subunit of the CdI4 dianion with the cadmium atom observed on a crystallographic twofold axis. In the cation, four N atoms of two bidentate phenanthroline ligands and one iodo ligand form an approximately trigonal-bipyramidal arrangement around the Cu2+ ion, with atoms I3, N1 and N4 occupying equatorial positions whereas N2 and N3 occupy the axial positions (Fig. 1). The equatorial plane (Table 1) is distorted with angles of 124.07 (9)° (N1—Cu1—I3), 125.98 (9)° (N4—Cu1—I3), and 109.94 (13)° (N1—Cu1—N4). In the crystal structure of (I), the crystal packing is stabilized by intermolecular I—H interactions between I atoms of the anion and H atoms of the phenanthroline ligands with distances of 3.15 Å, as listed in Table 1. In addition, one of the iodine atoms of the anion (I1) is positioned over the adjacent ring of one of the phenanthroline ligands (C13—C17—C24) with a distance of 3.535 Å.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Considerable attention has been paid to heteronuclear metal complexes. At present, a variety of mixed metal complexes have been reported. (Chesnut et al., 1999. Ferbinteanu et al., 1998. Shiren et al., 2002.). Here, a new mixed metal complex is obtained under low temperature conditions. The asymmetric unit of the title compound, (I), contains one [CuI(phen)2]+ cation and a CdI2 subunit of the CdI4 dianion with the cadmium atom observed on a crystallographic twofold axis. In the cation, four N atoms of two bidentate phenanthroline ligands and one iodo ligand form an approximately trigonal-bipyramidal arrangement around the Cu2+ ion, with atoms I3, N1 and N4 occupying equatorial positions whereas N2 and N3 occupy the axial positions (Fig. 1). The equatorial plane (Table 1) is distorted with angles of 124.07 (9)° (N1—Cu1—I3), 125.98 (9)° (N4—Cu1—I3), and 109.94 (13)° (N1—Cu1—N4). In the crystal structure of (I), the crystal packing is stabilized by intermolecular I—H interactions between I atoms of the anion and H atoms of the phenanthroline ligands with distances of 3.15 Å, as listed in Table 1. In addition, one of the iodine atoms of the anion (I1) is positioned over the adjacent ring of one of the phenanthroline ligands (C13—C17—C24) with a distance of 3.535 Å.
