Figure 1
The molecular structure of (I), showing the atom-labeling scheme. Ellipsoids represent displacement parameters at the 40% probability level at ca 110 K. The Cu–bipyridine units reside on axes of twofold rotation at (, , z) (atoms Cu1, N17, C20, C21 and N24) and at (, −, z) (atoms Cu2, N25, C28, C29 and N32), and only the asymmetric unit is labeled. Hydrogen bonds are indicated by dashed lines. H atoms of the benzene and pyridyl rings have been omitted. |
