(2,9-Dimethyl-4,7-diphenyl-1,10-phen-anthroline-κN,N')bis-(thio-cyanato-κS)mercury(II).

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.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
