The crystal structure described by Pu4Zr crystallizes in the orthorhombic Fmmm space group. There are two inequivalent Pu sites. In the first Pu site, Pu(1) is bonded in a 8-coordinate geometry to two equivalent Pu(2), four equivalent Pu(1), and two equivalent Zr(1) atoms. In the second Pu site, Pu(2) is bonded in a 8-coordinate geometry to two equivalent Pu(1) and six equivalent Pu(2) atoms. Zr(1) is bonded in a 8-coordinate geometry to four equivalent Pu(1) and four equivalent Zr(1) atoms. is represented by the CIF card [CIF]
