Abstract (EN):
The title complex, [Cu(C12H9N2O)(C2H3O2)(C12H10N2O)], is a neutral Cu-II complex with a primary N3O2 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 center dot center dot center dot O, C-H center dot center dot center dot O and C-H center dot center dot center dot pi interactions.
