4-{[2-(2,4-Dinitro­phen­yl)hydrazinyl­idene](phen­yl)meth­yl}-5-methyl-2-phenyl-1H-pyrazol-3(2H)-one ethanol monosolvate

Abstract: In the title compound, C23H18N6O5·C2H6O, all three benzene rings lie in an approximate plane [maximum deviation = 0.2688 (16) Å] that makes an angle of 53.56 (3)° with the plane of the pyrazolone ring. Intra­molecular N-H...O hydrogen bonds occur. In the crystal, the ethanol solvent mol­ecule links adjacent mol­ecules through N-H...O-H...O hydrogen bonds, leading to an infinite chain along the c-axis direction. The ethyl group of the ethanol solvent mol­ecule is disordered over two set of sites in a 0.762 (5):0.238 (5) ratio.
