Crystal structure of N-[4-amino-5-cyano-6-(methyl-sulfan-yl)pyridin-2-yl]acetamide hemihydrate.

ABSTRACT: The title compound, C9H10N4OS·0.5H2O, crystallizes with two independent mol-ecules (A and B) in the asymmetric unit, together with a water mol-ecule of crystallization. The acetamide moiety, which has an extended conformation, is inclined to the pyridine ring by 7.95 (16)° in mol-ecule A and by 1.77 (16)° in mol-ecule B. In the crystal, the A and B mol-ecules are linked by two N-H⋯Ocarbon-yl hydrogen bonds, forming a dimer. The dimers are linked via N-H⋯N hydrogen bonds, forming ribbons that are linked by N-H⋯Owater hydrogen bonds to form sheets parallel to (110). The sheets are linked by O-H⋯N hydrogen bonds, forming slabs, and between the slabs there are weak slipped parallel π-π inter-actions [inter-centroid distance = 3.734 (2) Å, inter-planar distance = 3.3505 (11) Å and slippage = 1.
