Abstract:
The title compound, C24H22N4O5, crystallizes with two mol-ecules in the asymmetric unit (Z' = 2) oriented almost perpendicular to each other [dihedral angle between the central core of each mol-ecule = 77.95 (3)°]. The two mol-ecules exhibit similar conformations with an extended structure. An intra-molecular C-H⋯N hydrogen bond occurs in each mol-ecule. The two mol-ecules are linked by a bifurcated N-H⋯(O,N) hydrogen bond involving the NH group in mol-ecule A as donor. They are further linked into a ribbon along the a-axis direction by further bifurcated N-H⋯(O,N) hydrogen bonds involving the NH group in mol-ecule B as donor. C-H⋯O inter-actions are also observed.

Structures of Carboxylic Acid Derivatives
Carboxylic acid derivatives contain an acyl group attached to a heteroatom such as chlorine, oxygen, or nitrogen. The carbonyl carbon and oxygen are both sp2-hybridized with an unhybridized p orbital.
The three sp2 orbitals of the carbonyl carbon form three σ bonds, one each with the carbonyl oxygen, the α carbon, and the heteroatom, whereas the other two sp2 orbitals of the carbonyl oxygen are occupied by the lone pairs. Further, the unhybridized p...

Nomenclature of Carboxylic Acid Derivatives: Amides and Nitriles
The IUPAC and common names of amides are derived from the parent carboxylic acid, by replacing the suffix “oic acid” and “ic acid,” respectively, with “amide.” In the following example, the IUPAC name ethanamide is derived from ethanoic acid, and the common name, acetamide, is obtained from acetic acid.
Structure and Nomenclature of Alcohols and Phenols
Alcohols are one of the most important functional groups in organic chemistry. The name of alcohol comes from the hydrocarbon from which it is derived. Alcohols are organic molecules containing the functional hydroxyl or –OH group directly bonded to carbon. Phenols have an OH group directly attached to a benzene ring. While alcohols are colorless, phenol is a white crystalline compound with a characteristic "hospital smell" odor.
As with other organic compounds, alcohols and...
