ThGe2 is Zirconium Disilicide-like structured and crystallizes in the orthorhombic Cmmm space group. Th(1) is bonded in a 10-coordinate geometry to two equivalent Ge(2), two equivalent Ge(3), and six equivalent Ge(1) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 8-coordinate geometry to six equivalent Th(1) and two equivalent Ge(1) atoms. In the second Ge site, Ge(2) is bonded in a distorted body-centered cubic geometry to four equivalent Th(1) and four equivalent Ge(3) atoms. In the third Ge site, Ge(3) is bonded in a 8-coordinate geometry to four equivalent Th(1) and four equivalent Ge(2) atoms.
ThGe2 is Zirconium Disilicide-like structured and crystallizes in the orthorhombic Cmmm space group. Th(1) is bonded in a 10-coordinate geometry to two equivalent Ge(2), two equivalent Ge(3), and six equivalent Ge(1) atoms. Both Th(1)-Ge(2) bond lengths are 3.06 Å. Both Th(1)-Ge(3) bond lengths are 3.11 Å. There are four shorter (3.10 Å) and two longer (3.41 Å) Th(1)-Ge(1) bond lengths. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 8-coordinate geometry to six equivalent Th(1) and two equivalent Ge(1) atoms. Both Ge(1)-Ge(1) bond lengths are 2.55 Å. In the second Ge site, Ge(2) is bonded in a distorted body-centered cubic geometry to four equivalent Th(1) and four equivalent Ge(3) atoms. All Ge(2)-Ge(3) bond lengths are 2.89 Å. In the third Ge site, Ge(3) is bonded in a 8-coordinate geometry to four equivalent Th(1) and four equivalent Ge(2) atoms.
