Figure 1
Views of the two and a half independent molecules of the title compound in each asymmetric unit, showing the atom-numbering scheme and with displacement ellipsoids drawn at the 30% probability level. For clarity, coordination of Pb by anions primarily bonded to other PbII centres is not shown. The molecules containing Pb1 (a) and Pb2 (b) occupy general positions while Pb3 (c) lies on a crystallographic twofold axis which also bisects the central ring of the ligand. Atoms whose labels include the suffix `A' are related to their unsuffixed equivalents by the symmetry operation (1 − x, y, − z). |
