The hydrogensquarates of glycine‐containing tripeptides glycylglycylglycine (H‐Gly‐Gly‐Gly‐OH), glycylglycylmethionine (H‐Gly‐Gly‐Met‐OH), and methionylglycylglycine (H‐Met‐Gly‐Gly‐OH) have been characterized structurally. Quantum chemical ab initio calculations, solid‐state linear‐dichroic infrared (IR–LD) spectroscopy, 1 H and 13 C NMR data, ESI‐MS, HPLC‐MS/MS, TGV, and DSC methods were employed. The structures consist in a positively charged peptide moiety and a negative hydrogensquarate anion (HSq − ), stabilized by strong intermolecular hydrogen bonds. © 2006 Wiley Periodicals, Inc.
