Figure 2
A packing diagram for (I). Hydrogen bonds are shown as dashed lines (for D⋯A < 3 Å). For the sake of clarity, the methylene groups and the H atoms of the en ligands have been omitted. Atom O1′ is at the symmetry position (x, 1 + y, z) and atom O2′ is at the symmetry position (x, y, 1 + z). |
