- Abstract
Abstract: The formation of salts in the L-cysteine–HNO
3–H
2O system was studied yielding three representatives as single crystals: anhydrous L-cysteinium nitrate (L-CysH)NO
3 (I) and two new salts (L-CysH⋯L-Cys)NO
3 (II) and (L-CysH⋯L-Cys)NO
3∙0.5H
2O (III) with the dimeric (L-CysH⋯L-Cys) cation. (I), (II) and (III) crystallize in space groups P2

1, P2
1 and I2, respectively. Dimeric cations in (II) and (III) were formed by very short O–H⋯O hydrogen bonds with R(O⋯O) distances of 2.440(2) Å and 2.4352(17) Å, respectively. Infrared and Raman spectra of (I–III) were registered and discussed in relation to crystal structures. Characteristics of dimeric cations are compared with those in the previously obtained compounds of L-CysH(L-CysH⋯L-Cys)F(F⋯HF), (L-CysH⋯L-Cys)Cl, (L-CysH⋯L-Cys)Br and (L-CysH⋯L-Cys)I·0.5H
2O. [Figure not available: see fulltext.].
