In the crystal structure of the title complex, [Zn2Cl4(C12H8N2)2], each of the two five-coordinated ZnII atoms displays a strongly distorted trigonal-bipyramidal geometry defined by two N atoms from the chelate ligand and by one terminal and two bridging chloride anions. The crystal structure is stabilized by C—H⋯Cl interactions. There is intermolecular π–π stacking between adjacent phenanthroline ligands, with a centroid–centroid distance of 3.151 (3) Å.
For the use of metal complexes of phenanthroline and its derivatives with π-π stacking to study the hydrolysis of biologically important phosphate diesters with poor leaving groups, see: Wall et al. (1999 ▶). For the structures of a series of metal complexes, see: Wu et al. (2003 ▶); Pan & Xu (2004 ▶); Li et al. (2005 ▶). For bond-length data, see: Allen et al. (1987 ▶).
