The asymmetric unit of the title co-crystal, C6H7N3O·0.5C4H6O4, comprises one N'-hy-droxy-pyridine-2-carboximidamide mol-ecule and half a succinic acid mol-ecule (the whole molecule is generated by inversion symmetry). In the crystal, mol-ecules are assembled into columns along [110], via strong N-H⋯O, O-H⋯O and O-H⋯N hydrogen bonds.
