摘要
The trimorphic cocrystals of celecoxib with delta-valerolactam contain sulfonamide dimers and catemers together with carboxamide dimers, whereas the caprolactam cocrystal is sustained by a SO2N-H center dot center dot center dot H-NOC heterosynthon. The alternation of synthons with even-odd ring coformers offers a crystal engineering approach to sulfonamide-carboxamide cocrystals.
