(Received 2 January 2013; accepted 11 January 2013; online 19 January 2013)

The title compound, [HgCl2(C14H12N2)], consists of one 2,9-dimethyl-1,10-phenanthroline (dmphen) ligand chelating the HgII ion and two chloride ligands coordinating to the HgII ion, forming a distorted tetra­hedral environment. The dmphen ligand is nearly planar (r.m.s. deviation = 0.0225 Å). The dihedral angle between the normal to the plane defined by the HgII atom and the two Cl atoms and the normal to the plane of the dmphen ring is 81.8 (1)°.

Comment top

The coordination chemistry of mercury(II) with N-donor ligands is of interest due to applications as solid-state materials (Ramazani et al., 2005; Mahjoub et al., 2004). Hg(II) complexes with bidentate ligands have been obtained in which Hg(II) adopts higher coordination numbers such as complexes of 1,10-phenanthroline (Canty & Maker, 1976) and N-substituted pyrazole (Canty & Lee, 1982). The molecular structure of [HgCl2(C14H12N2)], along with the numbering scheme is shown in Fig. 1. HgCl2 is chelated by the bidentate phenanthroline molecule and that the coordination of the nitrogen and chlorine atoms about the Hg atom is essentially a distorted tetrahedral environment (Fig. 1).

Experimental top

The desired complex was prepared by mixting of mercury chloride (HgCl2, 39.7 mg,0.14 mmol) in methanol (10 ml) with dmphen (32.0 mg, 0.15 mmol) in dichloromethane (5 ml) is stirred for one houre at room temperature. The obtained solution was concentrated to about 2 ml underreduced pressure and mixed to 30 ml of diethyl ether. The white precipitate was filtered and dried. suitable colourless crystals were obtained by slow diffusion of diethyl ether into a solution of the complex in dichloromethane.

Refinement top

All nonhydrogen atoms were refined anisotropically.H atoms were positioned geometrically, with C-H = 0.93 and 0.96 Å for aromatic and methyl H, respectively, and constrained to ride on their parent atoms, with Uiso(H) = 1.2Ueq(C). Highest difference peak and hole are 1.81 and -1.83e/Å3 close to the Hg atom.

Special details top

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.
