In the title compound, [Hg(C6H5)(C13H9F2N4S)]·0.5CH2Cl2, the Hg(C6H5) units are twisted out of the planes of the thiocarbazonate ligands by 61.49 (10) and 67.79 (11)° in the two complex molecules comprising the Important geometrical parameters include Hg—C = 2.079 (4) and 2.087 (4) Å, Hg—S = 2.3869 (10) and 2.3889 (11) Å, and C—Hg—S = 166.42 (12) and 168.09 (13)°. Weak intramolecular Hg—N bonding interactions of 2.589 (4) and 2.626 (4) Å are observed. In the crystal, C—H⋯Cl, C—H⋯F, C—H⋯N, C—H⋯π and π–π [centroid–centroid distances = 3.648 (3) and 3.641 (3) Å] interactions, create parallel planes along [101].

Solvents (AR) purchased from Merck and reagents from Sigma-Aldrich were used without further purification. The para-fluoro derivative of dithizone, (p-FPhNHN)2CS), was prepared according to the procedure reported by Mirkhalaf et al. (1998). The synthesis and crystallization of the title compound was done according to a procedure earlier reported by von Eschwege et al. (2008).
All hydrogen atoms were positioned in geometrically idealized positions with C—H = 0.95 Å (aromatic) or 0.88 Å (methylene) and N—H = 0.86 Å (imine). All hydrogen atoms were allowed to ride on their parent atoms with Uiso(H) = 1.2Ueq(C/N). The highest residual electron density of 3.10 e.Å-3 is 1.13 Å from Hg2 and the deepest hole of -2.47 e.Å-3 is 0.89 Å from Hg1. Both represent no physical meaning. Several discrepant reflections were omitted (see _iucr_refine_instructions_details).
With the aim of investigating the influence of electron withdrawing groups on the photochromic (Irving et al., 1949; Webb et al., 1950) and redox reactions (von Eschwege et al., 2011) of dithizonatophenylmercury(II) complexes, a series of halogenated dithizones were synthesized and for the first time complexed with mercury. Deep orange-red needle crystals of the para-fluoro derivative, suitable for X-ray crystallography, were isolated from a dichloromethane solution overlaid with ethanol.
The
of the title compound contains two crystallographically independent mercury(II) molecules and one solvent molecule of dichloromethane (Fig. 1). Geometrical parameters of the two dithizonato complexes are fairly similar with Hg—C = 2.079 (4) / 2.087 (4) Å; Hg—S = 2.3869 (10) / 2.3889 (11) Å; and C—Hg—S = 166.42 (12)/ 168.09 (13)° for Hg1 and Hg2, respectively. The mercury coordination environments differ slightly and can be seen most prominently from the dihedral angles between the metal coordination plane vs. the plane formed by the dithizonato ligands (19.03 (8)° vs. 23.45 (8)° for Hg1 and Hg2, respectively). Differences between the two units are illustrated in Fig. 2 with a superimposed fit using Mercury (Weng et al., 2008a; Weng et al., 2008b). The root mean square deviation (RMSD) was calculated as 0.151 Å, and the maximum distance between two atoms = 0.333 Å.Several interactions C—H···X (X = Cl, F, N), C—H···Cg (Table 1) and Cg···Cg (Table 2) stabilizes the crystal packing, creating parallel planes along the [101] direction (Fig. 3).

Experimental. The intensity data was collected on a Bruker Apex DUO 4 K CCD diffractometer using an exposure time of 10 s/frame. A total of 2980 frames were collected with a frame width of 0.5° covering up to θ = 28.33° with 99.5% completeness accomplished. Analytical data: M.p. 208 °C; λmax (dichloromethane) 471 nm; 1H (300 MHz, CDCl3) 7.06 – 7.99 (13 H, m, 2 × C6H4F & 1 × C6H5). |
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. |

With the aim of investigating the influence of electron withdrawing groups on the photochromic (Irving et al., 1949; Webb et al., 1950) and redox reactions (von Eschwege et al., 2011) of dithizonatophenylmercury(II) complexes, a series of halogenated dithizones were synthesized and for the first time complexed with mercury. Deep orange-red needle crystals of the para-fluoro derivative, suitable for X-ray crystallography, were isolated from a dichloromethane solution overlaid with ethanol.
The asymmetric unit of the title compound contains two crystallographically independent mercury(II) molecules and one solvent molecule of dichloromethane (Fig. 1). Geometrical parameters of the two dithizonato complexes are fairly similar with Hg—C = 2.079 (4) / 2.087 (4) Å; Hg—S = 2.3869 (10) / 2.3889 (11) Å; and C—Hg—S = 166.42 (12)/ 168.09 (13)° for Hg1 and Hg2, respectively. The mercury coordination environments differ slightly and can be seen most prominently from the dihedral angles between the metal coordination plane vs. the plane formed by the dithizonato ligands (19.03 (8)° vs. 23.45 (8)° for Hg1 and Hg2, respectively). Differences between the two units are illustrated in Fig. 2 with a superimposed fit using Mercury (Weng et al., 2008a; Weng et al., 2008b). The root mean square deviation (RMSD) was calculated as 0.151 Å, and the maximum distance between two atoms = 0.333 Å.
Several interactions C—H···X (X = Cl, F, N), C—H···Cg (Table 1) and Cg···Cg (Table 2) stabilizes the crystal packing, creating parallel planes along the [101] direction (Fig. 3).
