4,6-Dimethoxy-2-(methylsulfanyl)pyrimidine–4-hydroxybenzoic acid (1/1)
The base molecule of the title co-crystal, C(7)H(10)N(2)O(2)S·C(7)H(6)O(3), 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 cry...

Sumario: | The base molecule of the title co-crystal, C(7)H(10)N(2)O(2)S·C(7)H(6)O(3), 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 R (2) (2)(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 R (2) (2)(8) ring motifs. The heterotetramers are further linked by weak C—H⋯O hydrogen bonds, forming a tape structure along [1-10]. |
