, showing (a) homomolecular chains of glycinium cations (blue in the electronic version of the paper) stretching along the c axis and (b) chains of semi-malonate anions (green) stretching along the b axis, with heteromolecular four-membered rings. Hydrogen bonds are shown by thin lines and H atoms not involved in hydrogen bonding have been omitted. [Symmetry codes: (i) −x + 1, −y + 1, −z + 1; (ii) x, −y + $[{1\over 2}]$ , z − $[{1\over 2}]$ ; (iii) −x + 2, −y + 1, −z + 2; (iv) −x + 1, y − $[{1\over 2}]$ , −z + $[{3\over 2}]$ .]
