The molecules pack in alternating stacks (Figure 1),
one propagating in the direction of the c axis, the other。

in the direction of the vector bisecting the angle R
between the b and c axes. Successive layers of the stacks
are arched in opposite directions, creating oval tunnels
in which the molecules are aligned with a 2.66 Å contact
between a hydrogen on the bicyclo[1.1.1.]pentane bridge
and a bipyridyl nitrogen. There is a 2.79 Å close contact
between a hydrogen on a pyridine ring of one stack and
a nitrogen of a pyridine ring of a stack of the other
orientation. The acetylenic hydrogen appears to form a
2.50 Å long hydrogen bond to the center of the outer
aromatic ring of a neighbor molecule, slightly bent at
160.8°.
