title: 4,4'-Bipyridine acetic acid disolvate.
abstract: The crystal structure of the title compound, C(10)H(8)N(2)·2C(2)H(4)O(2), is built up from 4,4'-bipyridine and acetic acid mol-ecules linked by strong O-H⋯N hydrogen bonds. The 4,4'-bipyridine and the two acetic acid mol-ecules are further connected through weak C-H⋯O hydrogen bonds to form a supra-molecular two-dimensional network parallel to the (001) plane. The two pyridine rings make a dihedral angle of 31.8 (1)°.
