(Received 5 November 2012; accepted 9 November 2012; online 24 November 2012)

The base mol­ecule of the title co-crystal, C7H10N2O2S·C7H6O3, is essentially planar, with a maximum deviation of 0.0806 (14) Å for all non-H atoms. The acid mol­ecule is also nearly planar, with a dihedral angle of 8.12 (14)° between the benzene ring and the carb­oxy group. In the crystal, the acid mol­ecules form an inversion dimer through a pair of O—H⋯O hydrogen bonds with an R22(8) ring motif. The pyrimidine mol­ecules are linked on both sides of the dimer into a heterotetra­mer via O—H⋯N and C—H⋯O hydrogen bonds with R22(8) ring motifs. The heterotetra­mers are further linked by weak C—H⋯O hydrogen bonds, forming a tape structure along [1-10].

Comment top

Pyrimidine and aminopyrimidine derivatives are biologically important compounds as they occur in nature as components of nucleic acids. Some aminopyrimidine derivatives are used as antifolate drugs (Hunt et al., 1980; Baker & Santi, 1965). 2-Thiopyrimidine shows a strong bacteriostatic activity in vitro on E. coli (Holy et al., 1974). 4-Hydroxybenzoic acid is a good hydrogen-bond donor and can form co-crystals with other organic molecules (Vishweshwar et al., 2003). We have recently reported the crystal structures of 4,6-dimethoxy-2-(methylsulfanyl)pyrimidine (Balasubramani & Fun, 2009) and 4,6-dimethoxy-2-(methylsulfanyl)pyrimidinium chloride (Hemamalini & Fun, 2010). In order to study some potential hydrogen bonding interactions the crystal structure determination of the title compound (I) was carried out.

The asymmetric unit (Fig. 1), contains one 4,6-dimethoxy-2-(methylsulfanyl)pyrimidine molecule and one 4-hydroxybenzoic acid molecule. The 4,6-dimethoxy-2-(methylsulfanyl)pyrimidine molecule is planar, with a maximum deviation of 0.0806 (14) Å of atom C5 from a mean plane of all non-H atoms. The carboxy group of the 4-hydroxybenzoic acid molecule is slightly twisted from the attached ring by 8.12 (14)°. The bond lengths (Allen et al., 1987) and angles are normal.

In the crystal packing (Fig. 2), the 4-hydroxybenzoic acid molecules are centrosymmetrically paired through a pair of O4—H1O4···O3i hydrogen bonds (symmetry code in Table 1) to form an R22(8) (Bernstein et al., 1995) ring motif. In addition, the 4,6-dimethoxy-2-methylthiopyrimidine molecule and 4-hydroxybenzoic acid molecule are linked via intermolecular O5—H1O5···N1ii and C9—H9A···O1ii hydrogen bonds (symmetry code in Table 1), generating R22(8) ring motifs. The crystal structure is further stabilized by weak C12—H12A···O2iii hydrogen bonds (symmetry code in Table 1), forming a supramolecular tape.

Experimental top

Hot methanol solutions (20 ml) of 4,6-Dimethoxy-2-methylthiopyrimidine (46 mg, Aldrich) and 4-hydroxybenzoic acid (39 mg, Merck) were mixed and warmed over a heating magnetic stirrer hotplate for a few minutes. The resulting solution was allowed to cool slowly at room temperature and single crystals of the title compound (I) appeared after a few days.

Refinement top

O-bound H atoms were located in a difference Fourier maps. Atom H1O5 was refined freely, while atom H1O4 was refined with a bond length restraint O—H = 0.85 (1) Å [refined distances: O5—H1O5 = 0.79 (3) Å and O4—H1O4 = 0.862 (10) Å]. The remaining H atoms were positioned geometrically (C—H = 0.95 and 0.98 Å) and were refined using a riding model, with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(methyl C). A rotating-group model was used for the methyl group. In the final refinement, five outliers were omitted (-2 -6 2, -3 6 3, 4 -5 1, -3 5 1 and 3 6 0).

Special details top

Experimental. The crystal was placed in the cold stream of an Oxford Cryosystems Cobra open-flow nitrogen cryostat (Cosier & Glazer, 1986) operating at 100.0 (1) K.

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.
