Bonding motifs present in the crystal structure of Hm1-. (a) Hydrogen-bonding interactions forming two-dimensional planes of molecules. (b) Stacking interactions present in the crystal structure. Molecules are coloured according to their symmetry equivalence as green (1) and blue (2). [Symmetry codes: (i) −x, y − $[{1\over 2}]$ , −z + $[{1\over 2}]$ ; (ii) x, −y + $[{1\over 2}]$ , z + $[{1\over 2}]$ ; (v) −x, y + $[{1\over 2}]$ , −z + $[{1\over 2}]$ ; (vi) −x + 1, −y + 1, −z + 2; (vii) −x + 1, −y, −z + 2; (viii) −x, −y, −z + 1; (ix) −x + 1, −y + 1, −z + 1.]
