Dear Sonu kumar Just to add some additional links apart from prof Eyvaz and Michael J. Mehl suggestions.
If you want to know the atom positions of particular element or alloys its necessary to know atleast one among the following three 1. Space group symbol 2. Structure symbol 3. Pearson symbol which you will observe in the link given by Prof Eyvaz....(nrl-navy) If you know space group symbol please try this link ...very handy and easy to work with.... http://cci.lbl.gov/cctbx/explore_symmetry.html hope this helps With regards K.
