Аннотация
The title compound, (C 8 H 10 N 3 )[Ce(C 7 H 3 F 3 NO 2 S) 4 ], crystallizes with two cations and two anions in the asymmetric unit, with ion pairs linked by N—H...O hydrogen bonds. The Ce 3+ cations adopt near regular square-antiprismatic coordination geometries, arising from four O , O -bidentate ligands. Numerous N—H...F hydrogen bonds, as well as weak contacts such as C—H...F and C—H...N interactions occur in the extended structure. Hirshfeld surface analysis indicates that 34.8% of intermolecular interactions are attributed to F...H/H...F, 13.2% to H...C/C...H, 11.1% to H...H, 6.6% to H...S/S...H and 5.5% to H...O/O...H contacts.
