Abstract: The asymmetric unit of the title co-crystal, C6H7N3O·0.5C4H6O4, comprises one N'-hydroxypyridine-2-carboximidamide molecule and half a succinic acid molecule (the whole molecule is generated by inversion symmetry). In the crystal, molecules are assembled into columns along , via strong N-HO, O-HO and O-HN hydrogen bonds.
