  1. In the title double proton-transfer salt, C 12 H 12 N 2 2+ ·2C 8 H 7 O 4 − , consisting of a 1:2 ratio of 4,4'-(ethene-1,2-diyl)dipyridinium cations ( trans bipyridinium ethylene) to 2-hydroxy-3-methoxybenzoate anions ( o -vanillate), the complete cation is generated by crystallographic inversion symmetry and it is linked to adjacent o -vanillate anions by N—H...O hydrogen bonds, forming trimolecular assemblies. The trimers are linked by C—H...O hydrogen bonds as well as aromatic π–π stacking interactions into a three-dimensional network. The anion features an intramolecular O—H...O hydrogen bond.

  2. The title triphenylamine derivative, C 24 H 17 Cl 2 N, featuring a 3,5-dichloro-1,1′-biphenyl moiety has been synthesized and structurally characterized. The molecular structure shows rotations of the phenyl rings in the range of 37–40° from the amine plane. In the crystal, the molecules interact by van der Waals interactions.
