The structure described by Pu2Tc3Si4 crystallizes in the monoclinic P2_1/c space group. Pu(1) is bonded in a 10-coordinate geometry to two equivalent Tc(1), two equivalent Tc(2), four equivalent Si(1), and four equivalent Si(2) atoms. There are two inequivalent Tc sites. In the first Tc site, Tc(1) is bonded in a 10-coordinate geometry to four equivalent Pu(1), two equivalent Si(2), and four equivalent Si(1) atoms. In the second Tc site, Tc(2) is bonded in a 7-coordinate geometry to two equivalent Pu(1), two equivalent Si(1), and three equivalent Si(2) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 10-coordinate geometry to four equivalent Pu(1), two equivalent Tc(1), two equivalent Tc(2), and two equivalent Si(1) atoms. In the second Si site, Si(2) is bonded in a 8-coordinate geometry to four equivalent Pu(1), one Tc(1), and three equivalent Tc(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
