Figure 1
The asymmetric units of (a) (I)[link] and (b) (II)[link], showing the atomic numbering schemes. Displacement ellipsoids are drawn at the 50% probability level and H atoms are shown as small spheres of arbitrary radii. Only one position of the disordered NH3+ group is shown. [Symmetry codes: (i) 1 − x, 1 − y, z; (ii) x, y, −1 + z; (iii) 1 − x, −y, z; (iv) 1 − x, −y, −1 + z; (v) x, −1 + y, z; (vi) −x, −1 + y, [{1\over 2}] − z; (vii) −x, y, [{1\over 2}] − z.]
