Synthesis and X-ray diffraction study of some nickel(II) complexes of urea and thiourea

Abstract

XRD of four biologically important nickel(II) complexes having urea and thiourea as primary ligands and sulphate and nitrate as secondary ligands have been studied using Bruker D8 Advance diffractometer at IUC, Indore. The synthesized metal complexes were characterized by XRD measurements in order to elucidate their geometry. The data obtained has been preceded using XRD data analysis program Origin 6.0 Professional. From the experimental measurements, various parameters, e.g., particle size, lattice parameter have been estimated.Particle size for Ni-urea complexes is found in the range of 4.23-9.01 nm while for Ni-thiourea complexes its range is 0.26-9.76 nm.Lattice parameter for all these complexes is found in the range of 7.47-8.06 A˚.The XRD analysis revealed the crystalline nature of all the complexes.
