2-[2-(2-Carboxyphenyl)hydrazinylidene]-3-oxo-N-phenylbutyramide
In the title compound, C(17)H(15)N(3)O(4), the mol-ecule is in the keto-hydrazone form. Intra-molecular N-H⋯O hydrogen bonds ensure that the mol-ecule is nearly planar (r.m.s. deviation of non-H atoms is 0.098 Å), with the two benzene rings forming a dihedral angle of 10.04 (2)°. In the crystal, inversion dimers are formed via pairs of O-H⋯O hydrogen bonds involving the -CO(2)H groups.
متن کاملrac-2-[2-(4-Fluorophenyl)-2-oxo-1-phenylethyl]-4-methyl-3-oxo-N-phenylpentanamide
The title compound, C(26)H(24)FNO(3), is a critical inter-mediate of a selective and competitive inhibitor of the enzyme 3-hy-droxy-3-methyl-glutaryl-coenzyme A (HMG-CoA) reductase. Inter-molecular N-H⋯O hydrogen bonding generates a chain along [give direction] that is the dominant inter-action in the crystal packing. Inter-molecular C-H⋯O inter-actions are also observed.
متن کامل2-(2-Chlorophenyl)-2-oxo-N-phenylacetamide
In the title compound, C(14)H(10)ClNO(2), the dihedral angle between the two rings is 59.4 (2)°. The two carbonyl groups are oriented almost anti-periplanar to each other, with a torsion angle of -160.43 (2)°. In the crystal, mol-ecules are linked into inversion dimers by pairs of N-H⋯O hydrogen bonds.
متن کامل2-Chloro-N-(2-chlorobenzoyl)-N-(2-ethyl-4-oxo-3,4-dihydroquinazolin-3-yl)benzamide
In the title compound, C24H17Cl2N3O3, the quinazolinone ring system is close to planar (r.m.s. deviation = 0.0132 Å), with the imide unit almost perpendicular to it, subtending a dihedral angle of 89.1 (1)°. However, the imide unit itself is not planar, the dihedral angle between the two O=C-N components being 34.6 (1)°. The dihedral angle between the two chlorobenzene rings is 40.50 (7)°, whil...
متن کاملEthyl N-(2-benzoyl-3-oxo-3-phenylpropanoyl)carbamate
In the title compound, C(19)H(17)NO(5), the dihedral angle between the phenyl groups is 79.55 (15)°. The terminal eth-oxy group is disordered over two orientations in a 0.873 (6):0.127 (6) ratio. In the crystal, mol-ecules are linked by N-H⋯O and C-H⋯O hydrogen bonds into [001] chains which incorporate R(1) (2)(6) loops. A very weak C-H⋯π contact also occurs.
