3-Benzamido-1-benzoyl-1H-pyrrol-2(5H)-one
In the title compound, C(18)H(14)N(2)O(3), one of the phenyl rings is almost coplanar with the pyrrole ring [dihedral angle = 2.56 (14)°], whereas the other one is tilted by 63.01 (6)° with respect to the pyrrole ring. Since the NH group is shielded from possible acceptors, this group is not involved in hydrogen bonding.
متن کاملCrystal structure of (3,5-dimethyl-1H-pyrrol-2-yl)diphenylphosphine oxide
The title compound, C18H18NOP, was obtained during a search for new P,N-containing ligands with the potential to generate precatalysts with chromium(III) for selective ethyl-ene oligomerization. In the crystal, mutual pairs of N-H⋯O=P hydrogen bonds link two mol-ecules into a dimer with individual mol-ecules related by a twofold rotation axis. The P=O bond length of 1.4740 (15) Å is not elongat...
متن کاملCrystal structure of 2-tert-butyl-2,3-dihydro-1H-benzo[c]pyrrol-1-one
The asymmetric unit of the title compound, C12H15NO, comprises two sym-metry-independent mol-ecules which differ mainly in the conformations of the tert-butyl groups. The mol-ecules contain an essentially planar five-membered 3-pyrroline ring incorporating a carbonyl substituent (pyrrolinone) which forms part of an isoindolinone skeleton. The planarity of the pyrrole ring is compared to other s...

In the title compound, C26H16N6O, the dihedral angles between the central pyrrole ring and the pendant indole ring system (r.m.s. deviation = 0.027 Å) and the azide-bearing benzene ring are 37.56 (8) and 51.62 (11)°, respectively. The azide group is almost coplanar with its attached benzene ring [C-C-N-N = 3.8 (3)°]. The benzoyl benzene ring is disordered over two orientations twisted with resp...
متن کامل2-Benzoyl-1H-benzimidazole
In the title compound, C(14)H(10)N(2)O, the benzoyl ring and benzimidazole ring system are aligned at a dihedral angle of 50.2 (2)°. In the crystal, inter-molecular N-H⋯N hydrogen bonds between adjacent imidazole groups generate supra-molecular C(4) chains running along the b axis.
