4,4'-Bipyridine-2-(carb-oxy-methyl-sulfan-yl)pyridine-3-carb-oxy-lic acid (1/1).

ABSTRACT: In the title co-crystal, C(10)H(8)N(2)·C(8)H(7)NO(4)S, the formate group is coplanar with the pyridyl ring of the acid [dihedral angle = 6.2?(7)°], while the carb-oxy-methyl-sulfanyl group makes a C-S-C-C torsion angle of 70.2?(1)° with the pyridine ring. The dihedral angle between the pyridyl rings of the 4,4'-bipyridine mol-ecule is 27.4?(1)°. The acid and the 4,4'-bipyridine mol-ecules are involved in hydrogen bonding via carb-oxy-lic O and pyridyl N atoms. The structure is further consolidated by inter-molecular C-H?O hydrogen bonds, generating a three-dimensional network.
