A view of the hydrogen-bonding motifs in (I). Aromatic H atoms have been omitted for clarity. Open circles represent C atoms, shaded circles O atoms and dotted circles Pb atoms. Pb—O coordination bonds are shown as open bonds. [Symmetry codes: (iv) 2 − x, + y, − z; (vi) x, − y, z − ; (vii) 2 − x, 1 − y, 1 − z; (viii) x, y + 1, z.] |
