Abstract: XRD analysis is used to identify the crystalline phases present in a material and thereby reveal chemical composition information. X-ray diffraction is useful for evaluating minerals, polymers, corrosion products, and unknown materials. In most cases, samples are analyzed by powder diffraction using samples prepared as finely ground powders. XRD analysis is performed by directing an x-ray beam at a sample and measuring the scattered intensity as a function of the outgoing direction, also called a diffraction pattern. The diffraction pattern characterize the crystal structure. X-Ray Diffraction analysis is used to determine crystalline structure parameters. The XRD measurements of all the samples have been carried out and characterized by 2.2 kw sealed Bruker D8 Advance X-ray diffractometer available at UGC DAE CSR, Indore, India. The data of all these samples have been processed by Origin computer software. The crystallite size and lattice parameter of the copper (II) mixed ligand complexes with 2-amino-3-hydroxypicolinamide have been reported. Keywords: Diffraction, copper, crystallite size, lattice parameter.
I. INTRODUCTION Transition metal ions are playing an important role in biological processes in the human body [1, 2]. For example, nickel (II), copper (II) and zinc (II) ions are the most abundant transition metals in humans. They are found either at the active sites or as structural components of a good number of enzymes [3, 4]. The study of the coordination chemistry of biologically important metal ions with mixed ligands has been one of the recent developments in the field of bioinorganic chemistry. The powder XRD analytical tool is used to determine the types crystal system, phase of crystal, space group, crystalline defects, crystallite size, lattice parameter, unit cell volume etc. This technique takes place when only the Bragg’s condition is fully satisfied. The crystallit size and lattice parameters of the Copper (II) mixed ligand complexes with 3-hydroxypicolinamide ligands have been estimated by the obtained XRD data [5-10].

EXPERIMENTAL
The XRD patterns of all Copper(II) mixed ligand complexes with 3-hydroxypicolinamide in the powder form have been recorded at room temperature with the collimated Cu Kα monochromatic X-rays of wavelength 1.54Å having voltage 40kV and maximum current 100mA and the angular range of the diffraction pattern 2θ in the range between to 0 and the 0.05 step size and the time 1sec per step have been kept during the XRD process [11,12]. The XRD measurements of all the samples have been carried out and characterized by 2.2 kw sealed Bruker D8 Advance X-ray diffractometer
