N-(Pyridin-4-yl)isonicotinamide(cas: 64479-78-3) belongs to amides. Because of the greater electronegativity of oxygen, the carbonyl (C=O) is a stronger dipole than the N–C dipole. The presence of a C=O dipole and, to a lesser extent a N–C dipole, allows amides to act as H-bond acceptors.“,” In primary and secondary amides, the presence of N–H dipoles allows amides to function as H-bond donors as well. Formula: C11H9N3O

Ross, Tamsyn M.; Neville, Suzanne M.; Innes, David S.; Turner, David R.; Moubaraki, Boujemaa; Murray, Keith S. published an article on January 7 ,2010. The article was titled 《Spin crossover in iron(III) Schiff-base 1-D chain complexes》, and you may find the article in Dalton Transactions.Formula: C11H9N3O The information in the text is summarized as follows:

Iron(III) 1-dimensional polymeric materials, [Fe(III)(Schiff-base)(L)](BPh4).n(CH3OH) (Schiff base = N,N’-ethylenebis(salicylaldimine) (H2salen), N,N’-o-phenylenebis(salicylaldimine) (H2salophen) and N,N’-ethylenebis(acetylacetonimine) (H2acen); L = bridging di-pyridyl or di-imidazole ligand, n = 0-4) and analogs therein, were synthesized and structurally and magnetically characterized. In this series, a range of structural motifs are observed including linear 1-dimensional chains, hydrogen-bonded chains, a ‘hybrid’ 1-dimensional chain-and -dimer compound and a hydrogen-bonded dinuclear material; all exhibit extensive intermol. interactions. The magnetic consequences of varying both the equatorial Schiff-base ligands and axial bridging ligands were studied. Overall, independent of the axial bridging ligand employed, the salen equatorial ligand results in a high spin character and the acen ligand results in spin crossover character, generally with a spin transition of a gradual nature. Variations in magnetic behavior can be rationalized, in part, in terms of the C2N2 backbone conformation of the equatorial Schiff base ligand, which may either inhibit or allow a spin transition. The experimental process involved the reaction of N-(Pyridin-4-yl)isonicotinamide(cas: 64479-78-3Formula: C11H9N3O)
