title: Pyrimidin-2-amine-1-phenyl-cyclo-pentane-1-carb-oxy-lic acid (1/1).
abstract: In the crystal structure of the title co-crystal, C(4)H(5)N(3)·C(12)H(14)O(2), the components are linked by N-H⋯O and O-H⋯N hydrogen bonds. Self-assembly of these dimeric units results in a four-component supra-molecular unit featuring a homosynthon between two mol-ecules of the pyrimidin-2-amine involving two N-H⋯O hydrogen bonds, and two heterosynthons between each one mol-ecule of pyrimidin-2-amine and 1-phenyl-cyclo-pentane-1-carb-oxy-lic acid involving N-H⋯O and O-H⋯N hydrogen bonds.
