Abstract:
The title complex, [Cu(C(12)H(9)N(2)O)(C(2)H(3)O(2))(C(12)H(10)N(2)O)], is a neutral Cu(II) complex with a primary N(3)O(2) coordination sphere. The Cu centre coordinates to both a deprotonated and a neutral molecule of N-phenylpyridine-2-carboxamide and also to an acetate anion. The coordination around the metal centre is asymmetric, the deprotonated ligand providing two N donor atoms [Cu-N = 1.995 (2) and 2.013 (2) Angstrom] and the neutral ligand providing one N and one O donor atom to the coordination environment [Cu-N = 2.042 (2) Angstrom and Cu-O = 2.2557 (19) Angstrom], the fifth donor being an O atom of the acetate ion [Cu-O = 1.9534 (19) Angstrom]. The remaining O atom from the acetate ion can be considered as a weak donor atom [Cu-O = 2.789 (2) Angstrom], conferring to the Cu complex an asymmetric octahedral geometry. The crystal structure is stabilized by intermolecular N-H...O, C-H...O and C-H...pi interactions.

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 Aryl and Heterocyclic Amines
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.
