title: A cocrystal of pyridine-2,4-dicarboxylic acid and serine.
abstract: The title compound, pyridine-2,4-dicarboxylic acid-S-serine (1/1), C(7)H(5)NO(4)·C(3)H(7)NO(3), has serine in its zwitterionic form. The crystal structure is stabilized by an extensive series of inter-molecular O-H⋯O, N-H⋯N and N-H⋯O hydrogen bonds, forming a three-dimensional network.
