Figure 2
Packing diagrams of 1·py at 95 K, with displacement ellipsoids drawn at the 50% probability level. (a) View along the ac diagonal, with the zigzag chain of the com­plex unit highlighted in orange and the direction in which the pyridine units propagate highlighted in blue. (b) Zoomed view of the arrangement of two neighbouring com­plexes, with close contacts annotated. (c) View approximately along c, highlighting the π-stacking between the solvate and the com­plexes. (d) View along the b axis. Only 1·py is shown, but the description applies to all isostructural com­pounds.
