The asymmetric unit of the title compound, [HgCl₂(C₂₆H₂₀N₂)]·0.5CH₃CN, contains two crystallographically independent [HgCl₂(C₂₆H₂₀N₂)] molecules and one acetonitrile solvent molecule. The Hg^II 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.

We report herein the synthesis and crystal structure of the title compound, (I).

The asymmetric unit of the title compound, (I), (Fig. 1) contains two crystallographically independent [HgCl₂(C₂₆H₂₀N₂)] molecules and one acetonitrile solvent molecule. The Hg^II atoms are four-coordinated in distorted tetrahedral configurations by two N atoms from 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline and two Cl atoms (Table 1). Rings A (N1/C2-C4/C11/C26), B (C11-C14/C25/C26), C (N2/C14/C15/C22/C23/C25) and F (N3/C28-C30/C37/C52), G (C37-C40/C51/C52), H (N4/C40/C41/C48/C49/C51) are, of course, planar and the dihedral angles between them are A/B = 4.00 (3), A/C = 6.08 (3), B/C = 3.52 (3) and F/G = 5.77 (3), F/H = 5.55 (3), G/H = 3.53 (3) °. So, the phenanthroline ring systems are not planar. The phenyl rings D (C5-C10), E (C16-C21) and I (C31-C36), J (C42-C47) are oriented at dihedral angles of D/E = 74.61 (3) and I/J = 66.00 (3) °.

In the crystal structure (Fig. 2), the π–π contacts between the phenanthroline rings, Cg1—Cg2ⁱ, Cg2—Cg2ⁱ, Cg1—Cg3ⁱ, Cg2—Cg9ⁱⁱ, Cg6—Cg7ⁱⁱⁱ, Cg6—Cg8ⁱⁱⁱ, Cg7—Cg7ⁱⁱⁱ, Cg11—Cg2ⁱ and Cg12—Cg7ⁱⁱⁱ, [symmetry codes: (i) 2 - x, 1 - y, -z, (ii) 2 - x, 1 - y, 1 - z, (iii) 2 - x, -y, 1 - z, where Cg1, Cg2, Cg3, Cg6, Cg7, Cg8, Cg9, Cg11 and Cg12 are centroids of the rings A (N1/C2-C4/C11/C26), B (C11-C14/C25/C26), C (N2/C14/C15/C22/C23/C25), F (N3/C28-C30/C37/C52), G (C37-C40/C51/C52), H (N4/C40/C41/C48/C49/C51), I (C31-C36), K (Hg1/N1/N2/C25/C26) and L (Hg2/N3/N4/C51/C52), respectively] may stabilize the structure, with centroid-centroid distances of 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.

Experimental top

For the preparation of the title compound, (I), a solution of 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline (0.36 g, 1.10 mmol) in HCCl₃ (20 ml) was added to a solution of HgCl₂ (0.30 g, 1.10 mmol) in acetonitrile (20 ml) and the resulting pale yellow solution was stirred for 20 min at room temperature. Then, it was left to evaporate slowly at room temperature. After one week, colorless needle crystals of the title compound were isolated (yield; 0.47 g, 72.0%).

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.
