2-(4-Chloro­phen­yl)-4-[1-(4-chloro­phen­yl)-3-methyl-1H-pyrazol-5-yl]-5-methyl-1H-pyrazol-3(2H)-one

The title compound, C(20)H(16)Cl(2)N(4)O, has two mol­ecules in the asymmetric unit. The two five-membered rings form a dihedral angle of 54.2 (3)° in one mol­ecule and 56.8 (3)° in the other independent mol­ecule. The amino group of the dihydro­pyrazolone unit of one mol­ecule acts as a hydrogen-bo...

Sumario:The title compound, C(20)H(16)Cl(2)N(4)O, has two mol­ecules in the asymmetric unit. The two five-membered rings form a dihedral angle of 54.2 (3)° in one mol­ecule and 56.8 (3)° in the other independent mol­ecule. The amino group of the dihydro­pyrazolone unit of one mol­ecule acts as a hydrogen-bond donor to the carbonyl group of the dihydro­pyrazolone system of the other mol­ecule. The resulting N—H⋯O hydrogen bonds generate a chain running along the c axis. The crystal selected was a pseudo-merohedral twin with a 44.9 (3)% twin component.
