The 22H16N6O6S2·2C2H6OS, consists of one half-molecule of the centrosymmetric thiourea derivative and one molecule of dimethyl sulfoxide (DMSO). The carbonyl group forms an intramolecular hydrogen bond with the NH group, creating a six-membered (C—N—C—N—H⋯O) ring. Two other N—H⋯O hydrogen bonds link one molecule of the thiourea to two molecules of DMSO.

(p-Nitro)benzoyl chloride (1.86 g, 10 mmol) was reacted with ammonium thiocyanate (1.14 g, 15 mmol) in CH2Cl2 (25 ml) solution under solid-liquid phase transfer catalysis, using polyethylene glycol-400 (0.18 g) as the catalyst, to give the corresponding (p-nitro)benzoyl isothiocyanate under stirring at the room temperature. This was followed by slow addition of 15 ml CH2Cl2 solution dissolved p-phenylenediamine (1.60 g, 0.01 mmol). The corresponding yellow compound precipitated immediately. The product was filtered, washed with water and CH2Cl2, dried, and recrystallized from THF to give the titled thiourea. Yield, 72.6%. m. p. 243 - 244 °C. Anal. Calc. for C22H16N6O6S2 (%): C, 50.38; H, 3.07; N, 16.02. Found: C, 50.27; H, 3.15; N, 15.99. Selected IR data (cm-1 , KBr pellet): 3341, 3191 (ν NH), 1675 (ν C=O), 1152 (ν C=S). 1H NMR (400 MHz, DMSO-d6, δ, p.p.m.): 8.05 (d, J = 17.2 Hz, 4H, ArH), 8.19 (d, J = 8.2 Hz, 4H, ArH), 8.34 (dd, J = 17.2, 7.2 Hz, 4H, ArH), 11.98 (s, 2H, NH), 12.42 (s, 2H, NH).
A DMSO solution of the thiourea was placed in a hexane atmosphere, after about one week, along with diffusion of hexane into the DMSO solution, yellow needle-shaped single crystals suitable for X-ray crystallographic analysis were obtained.
Non-H atoms were refined anisotropically. H atoms were treated as riding atoms with distances C—H = 0.96(CH2), or 0.93Å (CH),O—H = 0.86 Å, and Uiso(H) = 1.2Ueq(C) and 1.5Ueq(O).

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. |

Thiourea and its derivatives are of interest to us because of their varied biological activity as well as their ability to form strong H bonds as both donors and acceptors (Valdés-Martínez, et al., 2000; Jesus, et al., 2004, Burrows et al., 1997), and their tendency to coordinate with metal ions (Huang, et al., 2006; Foss, et al., 2004). In recent years, thioureas have been recognized as important neutral receptors because of their anion recognition properties (Zhang, et al., 2006) and for their ability to easily form intramolecular hydrogen bonds such as between the benzoyl (CO) and the N—H group of acylthioureas (Dong et al., 2006). In continuation of our previous studies on the synthesis and structural characterization of N-benzoyl-N'-(3-pyridyl)thiourea (II) (Dong, et al., 2006) and N,N'-(1,6-hexamethylene)-bis(benzoylthiourea) (Dong, et al., 2007), a novel bisbenzoylthiourea which crystallized as a dimethyl sulfoxide disolvate (I) has now been synthesized and structurally characterized.
The crystal structure of (I) is built up by one N, N'-(p-phenyl)-bis(p-nitro)benzoylthiourea molecule and two dimethyl sulfoxide solvent molecules. The carbonyl group of the thiourea forms an intramolecular hydrogen bond with the N—H group to form a six-membered (C/N/C/N/H/O) ring. The C=O bond length at 1.225 (5)Å is longer than the average C=O bond length (1.200 Å). This is most likely due to the intramolecular hydrogen bonding which is similar to the situation found in the structure of (II) (Dong, et al., 2006).
There are also N—H···O hydrogen bonds between N1 of the thiourea and the O atoms of the DMSO S=O groups which, together with other intermolecular C—H···O and C—H···S interactions, stabilize the three-dimensional structure of (I).
