Figure 1
A view of (I), showing the contents of the asymmetric unit and the atom-numbering scheme. Displacement ellipsoids are drawn at the 50% probability level. Atoms bound to Pb1 and adjacent Pb atoms are labelled. H atoms have been omitted for clarity. [Symmetry codes: (i) 2 − x, 2 − y, 2 − z; (ii) x, y − 1, z; (viii) 2 − x, 1 − y, 2 − z.] |
