The title dimethyl sulfoxide solvate, [Hg2(C12H9ClN2)I2]·C2H6OS, features tetra­hedrally and linearly coordinated HgII atoms. The distorted tetrahedral coordination sphere is defined by chelating N atoms that define an acute angle [69.6 (3)°] and two I atoms that form a wide angle [142.80 (4)°]. The linearly coordinated HgII atom [177.0 (4)°] exists with a donor set defined by C and Cl atoms. Secondary inter­actions are apparent in the crystal packing with the tetra­hedrally and linearly coordinated HgII atoms expanding their coordination environments by forming weak Hg⋯I [3.772 (7) Å] and Hg⋯O [2.921 (12) Å] inter­actions, respectively. Mercury-containing mol­ecules stack along the a axis, are connected by ππ inter­actions [inter-centroid distance between pyridine and benzene rings = 3.772 (7) Å] and define channels in which the dimethyl sulfoxide mol­ecules reside. The latter are connected by the aforementioned Hg⋯O inter­actions as well as C—H⋯I and C—H⋯O inter­actions, resulting in a three-dimensional architecture.

Investigations in into the coordination chemistry of divalent zinc triad elements with (E)-N-(pyridin-2-ylmethylidene)arylamine ligands (Basu Baul, Kundu, Höpfl et al., 2013; Basu Baul, Kundu, Linden et al., 2013; Basu Baul, Kundu, Mitra et al. 2013) led to the isolation of the title compound, (I).

In (I), Fig. 1, the 2-[((4-chloromercuryl)phenyl)iminomethyl]pyridine, an organomercury ligand, chelates the Hg1 atom with the Hg1—N1(pyridyl) bond length being shorter than the Hg—N2(imino) bond in accord with related structures (Basu Baul, Kundu, Höpfl et al., 2013). The five-membered chelate ring is an envelope with the Hg1 atom lying 0.24 (2) Å out of the plane of the remaining four atoms (r.m.s. deviation = 0.0022 Å). In terms of angles, the major distortions from the ideal tetrahedral geometry about the Hg1 atom is found in the acute chelate angle (69.6 (3)°) and the wide angle subtended by the large I atoms (142.80 (4)°). The benzene ring carrying the HgCl atoms is almost co-planar to the pyridyl ring, forming a dihedral angle of 6.5 (6)°. The geometry about the Hg2 atom is linear as expected (177.0 (4)°).

In the crystal packing, centrosymmetrically related molecules associate via weak Hg···I secondary interactions: Hg1···I1i = 3.7027 (12) Å for symmetry operation i: -x, 1 - y, -z. These assemble into columns along the a axis via weak ππ interactions formed between the pyridyl and benzene rings [inter-centroid distance = 3.772 (7) Å for symmetry operation -1 + x, y, z]. In this way channels are formed in which reside the dimethyl sulfoxide molecules of solvation which are connected by weak Hg2···O1 secondary interactions [2.921 (12) Å] as well as weak C—H···I, O contacts, Fig. 2 and Table 2.

Experimental top

To a hot solution of 2-[((4-chloromercuryl)phenyl)iminomethyl]pyridine (0.50 g, 1.19 mmol) in methanol (70 ml) was added a solution of HgI2 (0.54 g, 1.18 mmol) in methanol (10 ml) under stirring conditions, whereupon a yellow precipitate formed immediately. The mixture was stirred at ambient temperature for 4 h. The precipitate was filtered, washed with hot methanol (3 x 5 ml) and dried in vacuo. The yellow product (0.79 g, M. pt. 495–497 K (dec.)) so obtained was insoluble in common organic solvents. The yellow crystals of compound suitable for an X-ray crystal-structure determination were obtained from dimethyl sulfoxide by slow evaporation of the solvent at room temperature. M. pt. 447–449 K. CH&N elemental analysis, calculated for C14H15ClHg2I2N2OS: C, 17.69, H, 1.59, N, 2.95%; Found: C, 17.82; H, 1.65; N, 3.07%.

Refinement top

Carbon-bound H-atoms were placed in calculated positions [C—H = 0.93 to 0.96 Å, Uiso(H) 1.2 to 1.5Ueq(C)] and were included in the refinement in the riding model approximation. The maximum and minimum residual electron density peaks of 4.39 and 1.45 e Å-3, respectively, were located 0.99 and 0.80 Å from the Hg1 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.
