Crystal structure of potassium 4-amino-5-(benzodthia­zol-2-yl)-6-(methyl­sulfan­yl)pyrimidin-2-yl(phenyl­sulfon­yl)aza­nide di­methyl­formamide monosolvate hemihydrate

摘要

The title compound, K⁺·C18H14N5O2S3 ⁻·C3H7NO·0.5H2O, was obtained in a reaction designed to deliver a neutral 2-pyrimidylbenzo­thia­zole. The anion is deprotonated at the sulfonamide nitro­gen. The asymmetric unit of the title compound contains two potassium cations, two anions, two mol­ecules of DMF and one of water. The anions display some conformational differences but each contains an intra­molecular N—H⋯Nbenzo­thia­zole hydrogen bond. The potassium ions both display a highly irregular six-coordination, different for each potassium ion. The anions, together with the DMF and water mol­ecules, are linked by four classical hydrogen bonds to form chains parallel to the b-axis direction.
