Weak C—H⋯π interactions between adjacent two-dimensional layers. For clarity, the acc dianions are simplified into long rods connecting the metal centres. The centroids (Cg) of the pyridyl rings of 4,4′-bpy are represented by black dots. [Symmetry codes: (v) −x + y, −x + 1, z + ; (vi) −y + 1, x − y + 1, z − .] |
