The compound described by PuB4 crystallizes in the orthorhombic Cmmm space group. There are two inequivalent Pu sites. In the first Pu site, Pu(1) is bonded in a 18-coordinate geometry to two equivalent B(4), four equivalent B(1), four equivalent B(2), four equivalent B(3), and four equivalent B(5) atoms. In the second Pu site, Pu(2) is bonded in a 18-coordinate geometry to two equivalent B(5), four equivalent B(1), four equivalent B(2), four equivalent B(3), and four equivalent B(4) atoms. There are five inequivalent B sites. In the first B site, B(1) is bonded in a 9-coordinate geometry to two equivalent Pu(1), two equivalent Pu(2), one B(5), two equivalent B(2), and two equivalent B(3) atoms. In the second B site, B(2) is bonded in a 9-coordinate geometry to two equivalent Pu(1), two equivalent Pu(2), one B(4), two equivalent B(1), and two equivalent B(3) atoms. In the third B site, B(3) is bonded in a 9-coordinate geometry to two equivalent Pu(1), two equivalent Pu(2), one B(3), two equivalent B(1), and two equivalent B(2) atoms. In the fourth B site, B(4) is bonded in a distorted trigonal planar geometry to two equivalent Pu(1), four equivalent Pu(2), one B(4), and two equivalent B(2) atoms. In the fifth B site, B(5) is bonded in a distorted trigonal planar geometry to two equivalent Pu(2), four equivalent Pu(1), one B(5), and two equivalent B(1) atoms. is represented by the CIF file [CIF]
