The most stable orientation of the disordered NMP molecule in 3. A short C—H⋯O contact is made to an S=O group of the neighbouring celecoxib molecule [symmetry code: (ii) x, −y + , z − ]. The less stable NMP orientation for 3 is shown as semi-transparent. A comparable C—H⋯O contact is seen for the most stable disorder component of DMPU in 5. |
