title: Dichlorido(2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline-κN,N')mercury(II) acetonitrile hemisolvate.
abstract: The asymmetric unit of the title compound, [HgCl(2)(C(26)H(20)N(2))]·0.5CH(3)CN, contains two crystallographic-ally independent [HgCl(2)(C(26)H(20)N(2))] mol-ecules and one acetonitrile solvent mol-ecule. The Hg(II) atoms are four-coordin-ated in distorted tetra-hedral configurations by two N atoms from 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline ligands and two Cl atoms. The ligand ring systems are not planar. The phenyl rings are oriented at dihedral angles of 74.61 (3) and 66.00 (3)° in the two molecules. In the crystal structure, π-π contacts between phenanthroline rings [centroid-centroid distances = 3.809 (1), 3.686 (1), 3.986 (1), 3.877 (1), 3.697 (1), 3.789 (1), 3.745 (1), 3.797 (1) and 3.638 (1) Å] may stabilize the structure.
