5-(2-Furyl)-3-methyl-1-(3-nitrophenyl)-4,5-dihydro-1H-pyrazole
In the title compound, C(14)H(13)N(3)O(3), the pyrazoline ring assumes an envelope conformation with the furanyl-bearing C atom at the flap position. The dihedral angle between the furan and nitrobenzene rings is 84.40 (9)°. Weak inter-molecular C-H⋯O hydrogen bonding is present in the crystal structure.

In the title mol-ecule, C(12)H(13)N(5)O(2)S, a bifurcated intra-molecular N-H⋯O(O) hydrogen bond forms two S(6) ring motifs. The benzene ring forms a dihedral angle of 14.36 (11)° with the pyrazole ring. In the crystal, pairs of N-H⋯S hydrogen bonds form centrosymmetric dimers, generating R(2) (2)(8) ring motifs, which stack along the b axis.

In the title compound, C(11)H(10)BrN(5)OS, the approximately planar pyrazole ring [maximum deviation = 0.014 (2) Å] forms a dihedral angle of 5.49 (13)° with the benzene ring. An intra-molecular N-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal, mol-ecules are linked through inter-molecular N-H⋯S and N-H⋯O hydrogen bonds, forming a two-dimensional network parallel to (100). A sho...

In the title compound, C(16)H(15)N(3)O(2), the planar [maximum deviation 0.156 (2) Å] pyrazoline ring is nearly coplanar with the 3-nitro-phenyl group and is approximately perpendicular to the phenyl ring, making dihedral angles of 3.80 (8) and 80.58 (10)°, respectively. Weak inter-molecular C-H⋯O hydrogen bonding is present in the crystal structure.
