3,5-Bis(2,4-dinitrophenyl)-4-nitro-1H-pyrazole acetone monosolvate

چکیده
The title structure, C(15)H(7)N(7)O(10)·C(3)H(6)O, was prepared by penta-nitration of 3,5-diphenyl-1H-pyrazole. The proton attached to a pyrazole N atom forms a hydrogen bond with the O atom of the acetone solvent mol-ecule, owing to the NO(2) enhanced acidity of the proton. The NO(2) group on the phenyl C atom is twisted by 33.9 (2)° from coplanarity with the ring in order to avoid a short intra-molecular O⋯O contact with an O atom of an adjacent pyrazole-bonded NO(2) group.

In the title mol-ecule, C(21)H(14)N(4)O(4)S, the pyrazole ring forms dihedral angles of 45.6 (1), 87.7 (1) and 27.4 (1)° with the phenyl, sulfur-substituted benzene and nitro-substituted benzene rings, respectively. In the crystal, mol-ecules are connected by weak C-H⋯O and C-H⋯N hydrogen bonds into layers parallel to (010).

Two different heterocycles, a pyrazole and an oxadiazine, are formed by the reactions of a common precursor, (2RS,3SR)-2,3-dibromo-1,3-bis(4-fluorophenyl)propan-1-one, with different simple hydrazines. In 3,5-bis(4-fluorophenyl)-1-phenyl-1H-pyrazole, C(21)H(14)F(2)N(2), (I), formed using phenylhydrazine, there is some aromatic-type delocalization in the pyrazole ring, and the molecules are link...

In the title compound, [Fe(C(5)H(5))(C(15)H(11)N(4)O(4))], the dinitro-phenyl and cyclo-penta-dienyl rings make dihedral angles of 53.61 (6) and 23.11 (9)°, respectively, with the pyrazole unit. The two cyclo-penta-dienyl rings are in an eclipsed conformation. The crystal structure is stabilized by inter-molecular C-H⋯O inter-actions, which link mol-ecules into chains parallel to the b axis.
