Recently, we have discovered a new class of amino acids salts containing different amino acids. In the present paper, we report crystal structures of three isostructural salts: l -argininium( +) sarcosine chloride (I), l -argininium( +) sarcosine bromide (II), and l -argininium( +) sarcosine iodide (III), formed by slow evaporation at room temperature from aqueous solutions containing stoichiometric ratios of components. The compounds crystallize in the polar space group P 2 1 with two formula units in the asymmetric unit. The structures are stabilized due to N–H···O and N–H···X (X = Cl, Br, I) hydrogen bonds. Infrared spectra of all three crystals are shown and discussed.
