Synthesis and crystal structure of Ni (II) metal organic framework with 2-Acetylpyridine isonicotinoyl hydrazone and Cambridge Structural Database studies

A metal organic framework of nickel with a hydrazone Schiff base ligand was synthesized and studied using a one-step method for synthesis and crystallization (lateral branching method). Infrared analysis combined with elemental analysis indicated that the desired compound was formed. Determining the structure of single crystals produced by X-ray crystallography shows the deformed octahedral structure surrounding the nickel atom, a nitrogen atom of the pyridine ring and the other of the amine, which is complemented by O atom from amide bonding of the coordination sphere. The data from the Cambridge Crystallography database is representative of 12569 combinations reported with the NiN6O2 unit, which suggests the excessive desire of the nickel atom to nitrogen atoms. The study of the length of the bonding length around the nickel atom indicates the correspondence of the reported data. Regarding the presence of the pyridine ring as the hydrogen bond acceptor, the three-dimensional structure is obtained which is empty.
