Thiophene-2-carbaldehyde N-(2,4-dinitrophenyl)-N-methylhydrazone

Molecules of the title compound, C12H10N4O4S, are linked through intermolecular hydrogen bonds to form a dimeric structure. The crystal structure of the dimer is stabilized by two intermolecular hydrogen bonds of the C-H...O type. The C...O intermolecular contact distance is 3.339(3) A, and the C=N and N-N distances are 1.279(2) and 1.371(7) A, respectively. One O atom of the 2-nitro group is disordered over two sites.
