The structure described by Th2GeSi crystallizes in the orthorhombic Pmc2_1 space group. There are two inequivalent Th sites. In the first Th site, Th(1) is bonded in a 7-coordinate geometry to three equivalent Ge(1) and four equivalent Si(1) atoms. In the second Th site, Th(2) is bonded in a 7-coordinate geometry to four equivalent Ge(1) and three equivalent Si(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to three equivalent Th(1), four equivalent Th(2), and two equivalent Si(1) atoms. Si(1) is bonded in a 9-coordinate geometry to three equivalent Th(2), four equivalent Th(1), and two equivalent Ge(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
