Creatininium 2-chloro­acetate


IN THE TITLE COMPOUND (SYSTEMATIC NAME 2-amino-1-methyl-4-oxo-4,5-dihydro-1H-imidazol-3-ium 2-chloro-acetate), C(4)H(8)N(3)O(+)·C(2)H(2)ClO(2) (-), the mol-ecular aggregations are stabil-ized through classical (N-H⋯O) and non-classical (C-H⋯O and C-H⋯N) hydrogen-bonding inter-actions. The cations are linked to the anions, forming ion pairs through two N-H⋯O bonds that produce characteristic R(2) (2)(8) ring motifs. These cation-anion pairs are connected through another N-H⋯O hydrogen bond, leading to an R(4) (2)(8) ring motif. Further weak C-H⋯N inter-actions link the mol-ecules along the a axis, while other C-H⋯O inter-actions generate zigzag chains extending along b.
