Crystal structure of 4,4 -(disulfanediyl)dibutanoic acid–4,4 -bipyridine (1/1)
MetadataShow full item record
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  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.
