在磺胺(SACT)和乙酰胺(ACT)的1:1共晶中,报道了一种罕见的含SO2-NH-CO分子的多态性。多晶型1中的R44(16)环基序通过N-H⋯OS和N-H⋯OC氢键组装,而由N-H⋯OC氢键组成的类似氢键环基序仅存在于形式2中。
A rare case of polymorphism in SO2–NH–CO containing molecules is reported in the 1 : 1 cocrystal of sulfacetamide (SACT) and acetamide (ACT). The R44(16) ring motif in polymorph 1 is assembled via N–H⋯OS and N–H⋯OC H-bonds whereas a similar hydrogen-bonded ring motif made of N–H⋯OC H-bonds only is present in form 2.
