Synthesis and Biological Composition of Cobalt (Ii) Complex With 2-Picolinic Acid

Abstract

The 2-picolinic acid (Hpic) cobalt(II) complex, namely [Co(pic)2 (H2O)2] as well as [H2O] as well, was synthesized through a solid-solid room temperature reaction with the cobald and 2-picolinic acid reactants. Single crystal X-ray diffractions and the thermogravimetry discrepancy scanning calorimetry describe the complex composition and structure (TG-DSC). The crystal structure of the complex performs in the P2(1)/n space scheme and cell community with a (or = 8.8468(7)A; = 5.2013(4)A; = 22.026 g cm -3; = 29.297; V = 32.11)A; The celtic structures belong to the monoclinic system and the space group P2(4)/n, cell parameters a = 9.8468(7)A; = 6.031(2)(13)(2)(3)(2); The Co(II) Ion, which shapes a somewhat twisted geometry of the octahedra, is coordinated six-way by two pyridine N atoms and two carboxyl O atoms of two 2-picolina Acid Anions, and two O atoms of two H2O molecules. The complex's thermal decomposition processes require the dehydration and pyrolysis of the ligand, and the cobalt oxalate is the ultimate residue at roughly 450 C.
