Figure 1 ORTEP representation of the coordination environment around the Zn centers, showing the atom-numbering scheme. Displacement ellipsoids are plotted at the 50% probability level. H atoms have been omitted for clarity [Symmetry codes: (a) −x, 1-y, −z; (b) 1/2-x, + y, 1/2-z; (c) 1/2-x, − + y, −1/2-z; (d) −x, 1-y, −z; e, −x, 1-y, −1-z]. |
