Resumen
4,40-(Disulfanediyl)dibutanoic acid (dtba) and 4,40-bipyridine (4,40-bpy) crystallize
in an 1:1 ratio, leading to the title co-crystal with composition
C8H14O4S2 C10H8N2. A distinctive feature of the crystal structure is the
geometry of the dtba moiety, which appears to be stretched [with a 9.98 (1) A ˚
span between outermost carbons] and acts as an hydrogen-bonding connector,
forming linear chains along [211] with the 4,40-bpy moiety by way of O—H N
hydrogen bonds and C—H O interactions. The influence of the molecular
shape on the hydrogen-bonding pattern is analysed by comparing the title
compound and two other 4,40-bpy co-crystals with closely related molecules of
similar formulation but different geometry, showing the way in which this
correlates with the packing arrangement.
