1-(5-Hydroxy-1-phenyl-3-trifluoromethyl-1H-pyrazol-1-yl)ethanone
The crystal structure of the title compound, C(12)H(9)F(3)N(2)O(2), contains two independent mol-ecules in the asymmetric unit. The mol-ecules are chemically identical but exhibit a significant difference in the dihedral angles between the mean planes of the phenyl and pyrazole rings, with values of of 11.62 (13) and 18.17 (11)°. Moreover, the trifluoro-methyl group in one of the mol-ecules sho...
متن کامل[5-Hydroxy-3-phenyl-1-(pyridin-2-yl)pyrazol-5-olato]diphenylboron
In the title compound, C(26)H(20)BN(3)O, the B atom has tetra-hedral geometry and is linked to two phenyl rings, the O atom of the hy-droxy-pyrazole ring and the N atom of the pyridinyl ring. A six-membered BOCNCN ring forms by coordination of the B atom and the pyridinyl N atom. The BOCNCN ring has an envelope conformation [dihedral angle = 36.7 (1)° between the planar ring atoms and the flap]...

In the title compound, C(11)H(12)N(4)O, the pyrazole and pyridine rings are nearly coplanar [dihedral angle = 1.87 (5)°]. Adjacent mol-ecules are linked by N-H⋯N and N-H⋯O hydrogen bonds into a linear chain running along the c axis.
متن کامل3-tert-Butyl-1-(3-nitrophenyl)-1H-pyrazol-5-amine
In the title compound, C(13)H(16)N(4)O(2), the pyrazole ring forms a dihedral angle of 50.61 (6)° with the 3-nitro-phenyl ring. The plane of the nitro group is twisted by 6.8 (7)° out of the plane of the phenyl ring. In the crystal, the mol-ecules are linked by N-H⋯N and N-H⋯O hydrogen bonds, forming sheets in the bc plane. In addition, a weak C-H⋯N inter-action is observed.
