The title compound, C 7 H 8 N 2 O 4 , is an important precursor of bi-or multidentate ligands. The structure contains two molecules linked together via intermolecular N-HÁ Á ÁO and N-HÁ Á ÁN hydrogen bonds and intermolecular C-HÁ Á ÁO contacts, resulting in a two-dimensional network. All atoms excep

## Abstract magnified image 5‐Hydrazinoquinoline and 8‐hydrazinoquinoline were converted __via__ Fischer syntheses with 3‐methyl‐butan‐2‐one into pyrido‐indolenines 2,3,3‐trimethyl‐3__H__‐pyrrolo[2,3‐__f__]quinoline **7** and 2,3,3‐trimethyl‐3__H__‐pyrrolo[3,2‐__h__]quinoline **11**, respectively.
In the title Schiff base, C 19 H 19 N 3 O 2 , the dihydropyrazole ring is essentially planar, with an r.m.s. deviation of 0.0289 A ˚for the fitted atoms. This ring makes dihedral angles of 41.8 (2) and 51.1 (3) with the phenyl and benzene rings, respectively. In the crystal structure, there is one i
