Abstract: | The crystal and molecular structure ofp-aminobenzene sulfonacetamide sodium, C8H9N2NaO3S·H2O, an important substituted sulfa drug, has been determined from diffractometric data using MoK radiation. The crystals are monoclinic, witha=6.614(2),b=23.788(6),c=7.012(2) Å, =103.13(2)°, and space groupP21/c. The structure was solved by the heavyatom method, and refined by full-matrix least squares to a finalR value of 0.040 with 1435 unique reflections. In packing, the molecules form dimers through pairs of N-H N and N-H O hydrogen bonds. The molecules are further stabilized by O-H O and O-H N hydrogen bonds. |
