Abstract
Abatract4,4′-Bipyridinium bis(trans-2-hydroxycinnamate) bis(4,4′-bipyridine), 0.5(C10H10N2)2+ (C9H7O3)−·C10H8N2, crystallizes in triclinic system, space group P-1, with a = 7.4211(8) Åb = 9.9516(11) Å, c = 13.8587(15)Å, β = 92.510(2)°, α = 96.772(2)°, γ = 99.164(2)°, V = 1001.33(19) Å3, ρcalc = 1.321 g/cm3, Z = 2. In the crystal, the whole trans-2-hydroxycinnamate is disordered over two sites with different occupancies. The molecular species are linked by O-H⋯N and N-H⋯O hydrogen bonds into five-molecule hydrogen bonded chain associates that are further linked by C-H⋯O hydrogen bonds into layers with the major orientation of the disordered 2-hydroxycinnamate. However such hydrogen bonds are not observed with the minor orientation.
