In the title compound, C(8)H(6)N(2)O(2), inter-molecular N-H⋯O hydrogen bonds involving the amine and carbonyl groups create centrosymmetric dimers between adjacent nearly coplanar mol-ecules. These dimers are further connected by weak N-H⋯O hydrogen bonds, forming a two-dimensional network. Mol-ecules are packed in the crystal structure with adjacent benzene and pyrimidine rings approximately coplanar; the centroid-centroid separation is 3.863 Å and the dihedral angle between the mean planes is ...[more]
