title: Methyl 4-amino-2,3-dihydro-6-methoxy-1,3-dioxo-1H-pyrrolo[3,4-c]-pyridine-7-carboxylate forms hydrogen-bonded sheets built from R2(2)(8) and R6(6)(42) rings.
abstract: In the title compound, C10H9N3O5, which was formed by the reaction of 6-amino-2-methoxy-4(3H)-pyrimidinone with dimethyl acetylenedicarboxylate, the molecules are linked by N-H...O hydrogen bonds [N...O 2.8974 (15) and 3.0300 (15) A, and N-H...O 165 and 174 degrees] into planar sheets built from alternating R2(2)(8) and R6(6)(42) rings.
