(2,9-Dimethyl-1,10-phenanthroline-?(2)N,N')bis-(thio-cyanato-?S)mercury(II).

ABSTRACT: The asymmetric unit of the title compound, [Hg(SCN)(2)(C(14)H(12)N(2))], contains two complex mol-ecules in which the Hg(II) atoms are both four-coordinated in a distorted tetra-hedral configuration by two N atoms from a chelating 2,9-dimethyl-1,10-phenanthroline ligand and by two S atoms from two thio-cyanate anions. The 1,10-phenanthroline ligand is slightly folded for one complex, the dihedral angle between the pyridine planes being 5.3?(1)°. In contrast it is nearly planar [0.5?(1)°] as it complexes with the other Hg(II) atom. The thio-cyanate ligands are virtually linear and the S atom is bonded to Hg(II) with N?S-Hg angles ranging from 99.3?(1) to 103.5?(1)°. Despite the presence of six aromatic rings in the asymmetric unit, there are no significant inter-molecular ?-? contacts between phenanthroline ligands as the centroid-centroid distance of the closest contact between six-membered rings is 4.11?(1) A°.
