Crystal structure of 4-[(2,4-dichlorophenyl)(5-hydroxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)methyl]-5-methyl-2-phenyl-2,3-dihydro-1H-pyrazol-3-one
In the title compound C27H22Cl2N4O2, the pyrazol-5-ol ring makes a dihedral angle of 34.80 (11)° with the phenyl ring to which it is bound, while the pyrazolone ring is inclined at 34.34 (12)° to its attached phenyl ring. In the crystal, N-H⋯O and C-H⋯Cl hydrogen bonds link the mol-ecules into chains along [010]. Inter-molecular π-π inter-actions are observed between the pyrazolone ring and the...
متن کامل4-(4-Bromo-3-methyl-1H-pyrazol-1-yl)-6-(but-3-ynyloxy)pyrimidine
There are two mol-ecules in the asymmetric unit of the title compound, C(12)H(11)BrN(4)O. The dihedral angles between the pyrazole and pyrimidine rings are 1.28 (17) and 1.56 (17)° in the two mol-ecules. In one of the mol-ecules, the but-3-yn-yloxy side chain is disordered over two sets of sites in a 0.714 (8):0.286 (8) ratio.
متن کاملCrystal structure of 3-bromo-2-hydroxybenzonitrile
The crystal structure of the title compound, C7H4BrNO, has been determined, revealing a partial mol-ecular packing disorder such that a 180° rotation of the mol-ecule about the phenol C-O bond results in disorder of the bromine and nitrile groups. The disorder has been parameterized as a disorder of only the bromine and nitrile substituents on a unique phenol ring. An intra-molecular O-H⋯Br con...
متن کاملCrystal structure of 4-bromo-N-(2-bromo-3-nitrobenzyl)-2-nitronaphthalen-1-amine
In the title compound, C17H11Br2N3O4, the dihedral angle between the planes of the naphthalene system and the benzene ring is 52.86 (8)°. The nitro substituent and the attached naphthalene system are almost coplanar [dihedral angle = 5.6 (4)°], probably as a consequence of an intra-molecular N-H⋯O hydrogen bond with the amine group. The nitro substituent attached to the benzene ring is disorder...

In the title compound, C13H8ClFN2, the dihedral angle between the plane of the benzimidazole ring system (r.m.s. deviation = 0.022 Å) and the benzene ring is 26.90 (8)°. The F atom at the meta position of the benzene ring is disordered over two sites in a 0.843 (4):0.157 (4) ratio. In the crystal, mol-ecules are linked by N-H⋯N hydrogen bonds, forming infinite C(4) chains propagating along [010...
