چکیده
In the mol-ecule of the title compound, [Hg(NCS)(2)(C(26)H(20)N(2))], the Hg(II) atom is four-coordinated in a distorted tetra-hedral configuration by two N atoms from a chelating 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline ligand and by two S atoms from two thio-cyanate anions. The ligand ring system is not planar. The dihedral angle between the phenyl rings is 53.20 (3)° . In the crystal structure, π-π contacts between phenanthroline rings [centroid-centroid distance = 3.981 (1) Å] may stabilize the structure.
