In the first Pu site, Pu(1) is bonded in a 17-coordinate geometry to three equivalent Tc(1), two equivalent B(2), two equivalent B(3), two equivalent B(4), two equivalent B(5), two equivalent B(6), and four equivalent B(1) atoms. In the second Pu site, Pu(2) is bonded in a 15-coordinate geometry to one Pu(2), two equivalent Tc(1), two equivalent B(2), two equivalent B(3), two equivalent B(4), two equivalent B(5), and four equivalent B(6) atoms. Tc(1) is bonded in a 15-coordinate geometry to two equivalent Pu(2), three equivalent Pu(1), two equivalent B(1), two equivalent B(2), two equivalent B(3), two equivalent B(4), and two equivalent B(5) atoms. There are six inequivalent B sites. In the first B site, B(6) is bonded in a 8-coordinate geometry to two equivalent Pu(1), four equivalent Pu(2), one B(2), and one B(4) atom. In the second B site, B(1) is bonded in a 9-coordinate geometry to four equivalent Pu(1), two equivalent Tc(1), one B(1), one B(2), and one B(5) atom. In the third B site, B(2) is bonded in a 9-coordinate geometry to two equivalent Pu(1), two equivalent Pu(2), two equivalent Tc(1), one B(1), one B(3), and one B(6) atom. In the fourth B site, B(3) is bonded in a 9-coordinate geometry to two equivalent Pu(1), two equivalent Pu(2), two equivalent Tc(1), one B(2), one B(4), and one B(5) atom. In the fifth B site, B(4) is bonded in a 9-coordinate geometry to two equivalent Pu(1), two equivalent Pu(2), two equivalent Tc(1), one B(3), one B(5), and one B(6) atom. In the sixth B site, B(5) is bonded in a 9-coordinate geometry to two equivalent Pu(1), two equivalent Pu(2), two equivalent Tc(1), one B(1), one B(3), and one B(4) atom. is represented by the CIF card [CIF]
