The material described by PuGa4 crystallizes in the monoclinic Cm space group. There are two inequivalent Pu sites. In the first Pu site, Pu(1) is bonded in a 13-coordinate geometry to one Ga(2), two equivalent Ga(3), two equivalent Ga(4), four equivalent Ga(1), and four equivalent Ga(5) atoms. In the second Pu site, Pu(2) is bonded in a 13-coordinate geometry to one Ga(3), two equivalent Ga(2), two equivalent Ga(5), four equivalent Ga(1), and four equivalent Ga(4) atoms. There are five inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 6-coordinate geometry to two equivalent Pu(1), two equivalent Pu(2), one Ga(4), one Ga(5), two equivalent Ga(2), and two equivalent Ga(3) atoms. In the second Ga site, Ga(2) is bonded in a 13-coordinate geometry to one Pu(1), two equivalent Pu(2), two equivalent Ga(5), four equivalent Ga(1), and four equivalent Ga(4) atoms. In the third Ga site, Ga(3) is bonded in a 13-coordinate geometry to one Pu(2), two equivalent Pu(1), two equivalent Ga(4), four equivalent Ga(1), and four equivalent Ga(5) atoms. In the fourth Ga site, Ga(4) is bonded in a 10-coordinate geometry to one Pu(1), two equivalent Pu(2), one Ga(1), one Ga(3), one Ga(4), two equivalent Ga(2), and two equivalent Ga(5) atoms. In the fifth Ga site, Ga(5) is bonded in a 10-coordinate geometry to one Pu(2), two equivalent Pu(1), one Ga(1), one Ga(2), one Ga(5), two equivalent Ga(3), and two equivalent Ga(4) atoms. is represented by the CIF file [CIF]
