N-[(5-Chloro-3-methyl-1-phenyl-1H-pyrazol-4-yl)carbonyl]-N′-(4-hydroxyphenyl)thiourea
In the title compound, C(18)H(15)ClN(4)O(2)S, the pyrazole ring makes dihedral angles of 67.4 (1) and 12.5 (1)° with the phenyl and 4-hydroxy-phenyl groups, respectively; the two benzene rings are twisted by 60.1 (1)° with respect to each other. The thio-urea NH groups are involved in N-H⋯O and N-H⋯Cl intra-molecular hydrogen bonds. A hydrogen bond between the phenolic OH group and the pyrazole...

The first crystal structure of a second-generation tris-(pyrazol-yl)methane, namely the title compound, C(31)H(28)N(6), is reported. The mol-ecule exhibits a helical conformation with an average twist of 35.1°. In addition, there are C-H⋯π inter-actions of 3.202 (2) Å between the pyrazole C-H group and neighbouring phenyl groups.
متن کامل4-(3-Methyl-5-phenyl-1H-pyrazol-1-yl)benzenesulfonamide
With respect to the planar five-membered ring of the title compound, C(16)H(15)N(3)O(2)S, the phenyl ring is aligned at 47.0 (1)° and the phenyl-ene ring at 37.6 (1)°. The amino group has the N atom in a pyramidal geometry; the group is a hydrogen-bond donor to the sulfonyl O atom of one mol-ecule and to the pyrazole N atom of another mol-ecule, resulting in the formation of a layer parallel to...
