Dichlorido(2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline-κ2 N,N′)mercury(II) acetonitrile hemisolvate

Abstract

The asymmetric unit of the title compound, [HgCl2(C26H20N2)]·0.5CH3CN, contains two crystallographic­ally independent [HgCl2(C26H20N2)] mol­ecules and one acetonitrile solvent mol­ecule. The HgII atoms are four-coordin­ated in distorted tetra­hedral 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
