- Abstract
Crystals of glycine hydrogen fluoride (Gly.HF) were prepared from an aqueous solution containing stoichiometricquantities of the components. The crystal structure of Gly.HF was determined, IR and Ramanspectra were registered and are discussed. Gly.HF crystallizes in the orthorhombic space group Pbca withZ = 32. The most remarkable feature of the structure is the existence of symmetric dimeric glycine-glyciniumcations with short hydrogen bonds (O...O distance of 2.446 Å), charge-counterbalanced by hydrogenbifluoride (F-H...F)_ anions - in addition to the expected glycinium cations and fluoride anions.These results were compared with previously published data on crystals grown in the system glycine-HF-H2O.
