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...

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...
متن کامل(±)-3-(5-Amino-3-methyl-1-phenyl-1H-pyrazol-4-yl)-2-benzofuran-1(3H)-one
In the title compound, C18H15N3O2, the benzo-furan ring system is essentially planar, the rings making a dihedral angle of 0.57 (9)°. The phenyl, furan and benzene rings subtend dihedral angles of 47.07 (10), 85.76 (7) and 86.04 (7)°, respectively, with the pyrazole ring. In the crystal, mol-ecules are linked by weak N-H⋯N, N-H⋯O and C-H⋯O inter-actions, generating edge-fused R 4 (4)(20), and R...
متن کاملEthyl 4-(5-chloro-3-methyl-1-phenyl-1H-pyrazol-4-yl)-6-methyl-2-oxo-1,2,3,4-tetrahydropyrimidine-5-carboxylate
In the title compound, C(18)H(19)ClN(4)O(3), the dihydro-pyrimidin-one ring adopts a flattened boat conformation. The dihedral angle between the phenyl and pyrazole rings is 43.39 (6)°. An intra-molecular C-H⋯O contact generates an S(8) ring motif that stabilizes the mol-ecular conformation and precludes the carbonyl O atom of the ester group from forming inter-molecular inter-actions. Mol-ecul...
