Synthesis and structural analyses of Bis(2-oxo-2,3-Dihydropyrimidin-1-ium) Tetrachloro zincate (II) [H2pymo][ZnCl4] and Bis(pyrimidin-2-olate) zinc(II) [Zn(pymo)2]

Abstract

The preparation of [H₂pymo][ZnCl₄] by reacting [H₂pymo]Cl and ZnCl₂ in the solid state is reported using the state of the arts techniques in crystal engineering and solid state methods. Single crystal X-ray diffraction revealed an orthorhombic crystal in the Pnma space group The structures of complex metal salt was studied and analysed using X-ray single crystal structure determination and X-ray powder diffraction (XRD) methods and elemental analyses were used to further characterize and establish the composition of the crystalline salts. Solid state mechanochemical methods were then explored to synthesize Bis(pyrimidin-2-olate) zinc(II) [Zn(pymo)₂] (a metal-organic framework) between zinc metal and pyrimidine ligands.
