The material described by PrLa(MnSi)4 crystallizes in the tetragonal P4/mmm space group. Pr(1) is bonded in a 16-coordinate geometry to eight equivalent Mn(1) and eight equivalent Si(2) atoms. La(1) is bonded in a 16-coordinate geometry to eight equivalent Mn(1) and eight equivalent Si(1) atoms. Mn(1) is bonded to two equivalent Pr(1), two equivalent La(1), two equivalent Si(1), and two equivalent Si(2) atoms to form a mixture of edge, corner, and face-sharing MnLa2Pr2Si4 tetrahedra. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 9-coordinate geometry to four equivalent La(1), four equivalent Mn(1), and one Si(1) atom. In the second Si site, Si(2) is bonded in a 9-coordinate geometry to four equivalent Pr(1), four equivalent Mn(1), and one Si(2) atom. is represented by the CIF card [CIF]
