Synthesis And Characterization of Two New Hofmann-Type-Like Compounds From Some Alkali Metal Atoms And Glycine Anhydride

Abstract

In this study, two new compounds with their closed formula, C8H10K2N6NiO4, and C8H10Na2N6NiO4, were synthesized, the first in crystal form and the second in powder form. Various properties of these compounds were characterized by SC-XRD and FT-IR methods. Theoretical information about the compounds was obtained with the help of the Gaussian 03 program. The molecular formula that best reflects the structural properties of this first 3D compound, which is in crystalline form and has polymeric properties, can be given as {K2(GA)(H2O)2[Ni(CN)4]}n. With a similar thought, it can be suggested that the molecular formula that best reflects the structural properties of the second 3D compound in powder form and with polymeric properties will be {Na2(GA)(H2O)2[Ni(CN)4]}n. The asymmetric unit of the {K2(GA)(H2O)2[Ni(μ4-CN)4]}n compound is composed of a half Ni(II) ion, one K(I) cation, two cyanide ligands, a half GA ligand molecule, and one bounded water ligand molecule. The structure of the compound, which consists of 3D polymeric chains, is formed by various bonds between the GA molecule, K(I) cations, water ligand molecules, and Ni(CN)4 ions.
