In this article the effect of hydrogen on structure of amorphous alloys of the form Ni0.243Zr0.757 Hy 0≤y≤0.25 is reported. The results of investigations on the structure of amorphous Ni0.243Zr0.757 and its hydrogenated sample are described. X-ray diffraction data are employed to calculate their radial distribution functions (RDF(r)) structures. The coordination umber of Ni-Zr metallic glass is determined as 10.6 and the hydrogen atoms in the hydrogenated amorphous Ni0.243Zr0.757H0.25 apparently prefer to occupy the tetrahedral hole surrounded mainly by 4 Zr atoms and a few by 3 Zr + 1 Ni atoms.
