چکیده
The title compound, C(5)H(7)N(3)O, was obtained by the reaction of ethyl 1H-pyrrol-2-carboxyl-ate and hydrazide hydrate. In the crystal, mol-ecules are linked via inter-molecular N-H⋯N and N-H⋯O hydrogen bonds, forming a supra-molecular grid.

In the title compound, C(12)H(12)N(4)O, the pyridine and pyrrole rings are inclined at an angle of 29.22 (8)° and an intra-molecular C-H⋯N inter-action geneates an S(6) ring. In the crystal, mol-ecules are linked by N-H⋯N hydrogen bonds, forming (010) C(7) chains. The chains are cross-linked by weak C-H⋯O inter-actions, which generate R(2) (2)(18) ring motifs within an infinite sheet. Finally, ...
