4,4′-Bipyridine acetic acid disolvate

Abstract

The crystal structure of the title compound, C10H8N2·2C2H4O2, is built up from 4,4′-bipyridine and acetic acid molecules linked by strong O—H...N hydrogen bonds. The 4,4′-bipyridine and the two acetic acid molecules are further connected through weak C—H...O hydrogen bonds to form a supramolecular two-dimensional network parallel to the (001) plane. The two pyridine rings make a dihedral angle of 31.8 (1)°.
