Figure 2 Two symmetry-related molecules in the crystal structure, omitting H atoms and non-coordinated nitrate ions. The blue plane is calculated using atoms Pb1/O1/O3/O4/O21 (spheres of arbitrary radii) and corresponds to the equatorial plane defining the hemidirected ligand arrangement. The short inter-cation contact is shown as a dashed line. Symmetry code: (i) 1 + x, y, z. |
