Figure 1
The extended asymmetric unit in I, showing the coordination environment of the Zn atoms and the atom-labelling scheme (displacement ellipsoids are drawn at the 30% probability level). C-bound H atoms have been omitted for clarity. Only one of two disordered components of the Zn2 cation is shown. Dotted lines represent intra-cation hydrogen-bonding interactions. [Symmetry codes: (i) −x + 2, −y, −z + 2; (ii) −x + 2, −y, −z + 1.] |
