原始语种摘要: In the title compound [systematic name: (1Z,3Z)-1,3-dihydrazinylidene-1H-inden-2(3H)-one], C 9 H 8 N 4 O, isolated molecules possess approximate noncrystallographic C 2v symmetry and their cis conformation and planarity are assisted by a pair of short intramolecular N—H...O hydrogen bonds. Each molecule is asymmetrically involved in an extensive three-dimensional network of N—H...O and N—H...N hydrogen bonds, and the structure also exhibits weaker π–π and C=O...C interactions. The structure features an R 4 4(12) motif consisting solely of N and H atoms and possessing crystallographic \overline{4} symmetry.
