Synthesis, Crystal Structure, Hirshfeld Surface Analysis, and DFT Calculations of Cesium Benzilate Monohydrate: Exploring the Importance of Noncovalent Interactions

Journal of Chemistry, Volume 2026, Issue 1, 2026.
The novel complex cesium benzilate monohydrate, Cs[C14H11O3]·H2O, was synthesized via the reaction of benzilic acid and cesium carbonate, and high‐purity single crystals were obtained by slow aqueous solvent evaporation. Powder X‐ray diffraction validated the crystalline phase purity.
