The crystal structure of an ionic compound consists of alternating cations and anions lying next to each other in three dimensions. If the cation radius is 55.9% of the anion radius and the distance between the cation nuclei is 580. pm, what are the radii of the two ions? (Note: This ionic compound is a three dimensional array. The cation to cation, center-to-center distance specified is through the center of the anion.)
anion
pm
cation

You really have to specify the specific crystal structure, among body-centered cubic, face-centered cubic, body-centered tetragonal, etc and etc.
Please refer to the following article:
