Preferred Abstract (Original):

In the title compound, [CdI2(C14H12N2)], the molecule sits on a crystallographic twofold axis. The coordination sphere of the CdII atom is built of two symmetry-equivalent N atoms of one 2,9-dimethyl-1,10-phenanthroline (dmphen) ligand and two symmetry-equivalent I atoms, thus forming a distorted tetrahedral geometry. Inversion-related molecules interact along the c-axis direction by π -π stacking interactions between the phenanthroline ring systems, with centroid-centroid distances of 3.707 (9) and 3.597 (10) Å.

Preferred Abstract (Original):

A binuclear nickel(II) chloride complex with dimethyl-1,10-phenanthroline, di-μ-chloro-bis[chloro(2,9-dimethyl-1,10-phenanthroline)nickel(II)] dimer, has been prepared and its molecular structure determined by X-ray diffraction. The crystal is triclinic, space group P−1, with the Ni(II) in [NiCl2(C14H12N2)]2 coordinated to two N of the phen ligand and three Cl−, one terminal and two bridging. A center of inversion lies midway between two Ni(II). Overall Ni(II) coordination is distorted triangular bipyramidal. The dimer complex was also characterized by elemental analysis, FAB-MS, IR and UV–visible spectroscopy, and thermogravimetric analysis.
