Abstract
We investigated salts formation in the DMG(dimethylglycine)HClH2O, DMGHBrH2O and DMGHIH2O systems. In addition to previously known dimethylglycinium chloride (DMGH)Cl, we obtained and characterized (structurally and spectroscopically) the following crystals: (DMGH)Br, (DMGH)I as well as the first salts of DMG with dimeric (DMG⋯DMGH) cation: (DMG⋯DMGH)Cl, (DMG⋯DMGH)Br, (DMG⋯DMGH)I. Obtained results are compared with results of known or newly obtained respective salts of glycine, sarcosine (monomethylglycine) and betaine (trimethylglycine).
