Figure 4
The hydrogen bonding environments of the hydrofumarate ion in the structure of (I)

(top), the hydrofumarate ion in the structure of (II)

(middle), and the fumarate dianion in the structure of (III)

(bottom). Displacement ellipsoids are drawn at the 50% probability level. Hydrogen atoms not involved in hydrogen bonds are omitted for clarity. Only one component of disorders are shown. Symmetry codes: (i) 1 + x, y, z; (ii) −1 + x, y, 1 + z; (iii) −1 + x, y, z; (iv) 2 + x, y, 1 + z; (v) 1 − x, 2 − y, 1 − z; (vi) $[{1\over 2}]$ − x, $[{1\over 2}]$ + y, $[{1\over 2}]$ − z; (vii) $[{1\over 2}]$ + x, $[{3\over 2}]$ − y, $[{1\over 2}]$ + z.
