Figure 2 a) The hydrogen–bonded chain structure of the title salt. H, O and Cl atoms involved in hydrogen bonding are are drawn as balls and O—H⋯Cl and N—H⋯Cl interactions are drawn as dotted lines. H atoms non–participating in hydrogen–bonding were omitted for clarity. b) Impterplay of classical hydrogen bonds (broken lines) and short O—H⋯X contacts (dotted lines); symmetry codes: (i) −x + 1, y + , −z + ; (ii) −x + , −y + 2, z − ; (iii) x + , −y + , −z + 1. |
