The title dimethyl sulfoxide (DMSO) solvate, C17H18N4O3·C2H6OS, shows the disubstituted urea derivative to adopt an almost planar geometry (r.m.s. deviation for non-H atoms = 0.132 Å); the molecule has non-crystallographic twofold molecular symmetry. This conformation is stabilized by two intramolecular O—H⋯N hydrogen bonds. The components of the crystal are connected by N—H⋯O hydrogen bonds, whereby both amine H atoms are connected to a DMSO O atom, and C—H⋯O contacts involving the DMSO H and urea carbonyl atoms, forming a supramolecular chain along the c axis. The chains associate via C—H⋯π interactions.

Carbohydrazide (0.90 g, 10 mmol) and 2-hydroxyacetophenone (2.72 g, 20 mmol) in dry methanol (40 ml) were heated at reflux for 4 h and cooled to ambient temperature. During cooling process, white microcrystals formed and were filtered off. The microcrystals, (I), were washed several times with small amounts of cold methanol and cold hexane. Crude (I) was recrystallized from methanol and dried in vacuo over silica gel. Yield: 1.99 g, 55%; m. pt. 467–468 K. Analysis. Calculated for C17H18N4O3: C, 62.56; H, 5.56; N, 17.17%. Found: C, 62.28; H, 5.61; N, 17.02%. UV-visible (DMSO) λmax: 282, 317, 382 nm.

Carbon-bound H-atoms were placed in calculated positions (C–H 0.95–0.98 Å) and were included in the
in the riding model approximation with Uiso(H) set to 1.2–1.5Ueq(C). The O– and N-bound H-atoms were located in a difference Fourier map and were refined with O–H and N–H restraints of 0.840±0.001 Å and 0.880±0.001 Å, respectively, and with Uiso(H) = 1.2Ueq(N) and 1.5Ueq(O).The title compound, (I), was prepared as a part of on-going studies into the biological activity of organotin compounds (Gielen & Tiekink, 2005; Affan et al., 2009). Crystals of (I) comprise equal quantities of a disubstituted urea molecule and a solvent dimethyl sulfoxide molecule, Fig. 1. The urea derivative, which has molecular twofold symmetry (non-crystallographic), is essentially planar as seen in the r.m.s. value of 0.132 Å for all non-H atoms. The arrangement is stabilized by two internal O–H···N hydrogen bonds, Table 1.
In the π contacts to consolidate the Table 1 and Fig. 3.
the two amine-H atoms form hydrogen bonds to the DMSO-O atom to generate a supramolecular dimer, Table 1. The dimers thus formed are connected into a supramolecular chain along the c axis via C–H···O contacts involving the carbonyl-O4 atoms and DMSO-H atoms, Table 1 and Fig. 2. The chains are connected by C–H···For background and recent studies on the biological activity of tin/organotin compounds, see: Gielen & Tiekink (2005); Affan et al. (2009).

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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 > 2σ(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. |

The title compound, (I), was prepared as a part of on-going studies into the biological activity of organotin compounds (Gielen & Tiekink, 2005; Affan et al., 2009). Crystals of (I) comprise equal quantities of a disubstituted urea molecule and a solvent dimethyl sulfoxide molecule, Fig. 1. The urea derivative, which has molecular twofold symmetry (non-crystallographic), is essentially planar as seen in the r.m.s. value of 0.132 Å for all non-H atoms. The arrangement is stabilized by two internal O–H···N hydrogen bonds, Table 1.
In the crystal structure, the two amine-H atoms form hydrogen bonds to the DMSO-O atom to generate a supramolecular dimer, Table 1. The dimers thus formed are connected into a supramolecular chain along the c axis via C–H···O contacts involving the carbonyl-O4 atoms and DMSO-H atoms, Table 1 and Fig. 2. The chains are connected by C–H···π contacts to consolidate the crystal structure, Table 1 and Fig. 3.
