Figure 2
Visualization of the HAR structures of the ibuprofen (a) and sila-ibuprofen (b) salts formed with PEA. Atomic displacement parameters are drawn at the 50% probability level. Both disorder parts are shown for both structures. In the ibuprofen structure, the R-enantiomer has 81.2 (7)% occupancy. In sila-ibuprofen, only the S-enantiomer is found and the disorder of the methyl groups is about 52/48%. The salt of ibuprofen was formed with S-PEA, while the sila-ibuprofen salt was formed with R-PEA. |
