1-[5-(2-Chlorophenyl)-5-hydroxy-3-methyl-4,5-dihydro-1H-pyrazol-1-yl]ethanone
The title compound, C(12)H(13)ClN(2)O(2), crystallizes with two independent but very similar mol-ecules (A and B) in the asymmetric unit. The pyrazole ring in each mol-ecule has an envelope conformation. The dihedral angle between the pyrazole ring mean plane and the benzene ring is 86.07 (14)° in A and 85.99 (14)° in B. In the crystal, the A and B mol-ecules are linked via a pair of O-H⋯O hydr...
متن کامل(Furan-2-yl)(5-hydroxy-3-methyl-5-phenyl-4,5-dihydro-1H-pyrazol-1-yl)methanone
In the title compound, C(15)H(14)N(2)O(3), the furan ring is disordered over two positions with a refined site-occupancy ratio of 0.587 (11):0.413 (11). The mean plane of the approximately planar pyrazole ring [maximum deviation = 0.0469 (11) Å] makes dihedral angles of 86.13 (11) and 4.5 (5)° with the phenyl and furan rings, respectively. The dihedral angle between the phenyl ring and the majo...

In the title mol-ecule, C(16)H(13)Cl(2)FN(2)OS, the dihedral angle between the thio-phene and benzene rings is 80.34 (12)°. The pyrazoline ring is in an envelope conformation, and the plane through the four coplanar atoms makes dihedral angles of 85.13 (9) and 6.89 (10)° with the thio-phene and benzene rings, respectively. The C and O atoms of the acetyl group are nearly coplanar with the attac...
متن کامل2-(4-Chlorophenyl)-4-[1-(4-chlorophenyl)-3-methyl-1H-pyrazol-5-yl]-5-methyl-1H-pyrazol-3(2H)-one
The title compound, C(20)H(16)Cl(2)N(4)O, has two mol-ecules in the asymmetric unit. The two five-membered rings form a dihedral angle of 54.2 (3)° in one mol-ecule and 56.8 (3)° in the other independent mol-ecule. The amino group of the dihydro-pyrazolone unit of one mol-ecule acts as a hydrogen-bond donor to the carbonyl group of the dihydro-pyrazolone system of the other mol-ecule. The resul...
