Methyl 3-methyl-5-oxo-4-(phenylhydrazono)-4,5-dihydro-1H-pyrazole-1-carbodithioate
The title compound, C(12)H(11)N(4)OS(2), has been synthesized by the condensation reaction of 3-oxo-2-(phenyl-hydrazono)butanate and S-methyl-dithio-carbazate. The hydrazine unit and the pyrazole ring are coplanar [dihedral angle 3.8 (4)°] due to extensive conjugation and the N-H⋯O=C intra-molecular hydrogen bond. Two adjacent mol-ecules form dimers due to short C-H⋯O=C [R(2) (2) (18)] and C-H⋯...
متن کامل4-[2-(4-Bromophenyl)hydrazinylidene]-3-methyl-5-oxo-4,5-dihydro-1H-pyrazole-1-carbothioamide
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(18)N(2)O(6), the dihedral angle between the aromatic ring planes is 8.11 (6)°. One of the O atoms is disordered over two sites of equal occupancy. In the crystal structure, aromatic π-π stacking [centroid-to-centroid separation = 3.5503 (8) Å] helps to consolidate the packing.

In the title mol-ecule, C(11)H(10)ClN(5)OS, an intra-molecular N-H⋯O hydrogen forms an S(6) ring motif. The dihedral angle between the pyrazole ring and the benzene ring is 3.77 (8)°. In the crystal, mol-ecules are linked by N-H⋯S and N-H⋯O hydrogen bonds into layers parallel to the bc plane.
متن کامل2-(4-Isopropyl-4-methyl-5-oxo-4,5-dihydro-1H-imidazol-2-yl)-5-methylnicotinic acid
In the title herbicideh/phytocide, known as imaza-pic, C(14)H(17)N(3)O(3), the pyridine and imidazole rings are almost coplanar [dihedral angle = 3.08 (5)°]. An intra-molecular O-H⋯N hydrogen bond occurs. In the crystal, an N-H⋯O hydrogen bond links mol-ecules into a chain parallel to [010].
