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 + $[{1\over 2}]$ , -z + $[{3\over 2}]$ ; (ii) -x + $[{1\over 2}]$ , -y + 2, z - $[{1\over 2}]$ ; (iii) x + $[{1\over 2}]$ , -y + $[{3\over 2}]$ , -z + 1.
