Packing diagram in views along (a) the vector a + c showing the π-stacked bipyridine-type ligands and (b) the cell vector c showing the layer-like arrangement. Dashed bright blue lines indicate hydrogen bonds. Unit-cell boundaries are depicted in black or red/green/blue marking the directions a/b/c, respectively. Symmetry code: (i) x − 1, y, z. |
