In the crystals of alkaline earth metal compounds strontium and barium with the non-steroidal anti-inflammatory drug nimesulide, the metal ions have different coordination spheres, TCTPR-9 and TCTPR-10, respectively.

The 2,3- O -isopropylidene group locks β- d -ribofuranosides in the E 0 -like conformation whereas ribonucleosides in the E 4 -like conformation. The conformational preferences of β- d -ribofuranosides are determined by the anomeric effect.
