ScHfGe4 is Zirconium Disilicide-derived structured and crystallizes in the orthorhombic Amm2 space group. Sc(1) is bonded in a 10-coordinate geometry to two equivalent Ge(2), two equivalent Ge(3), two equivalent Ge(4), and four equivalent Ge(1) atoms. Hf(1) is bonded in a 10-coordinate geometry to two equivalent Ge(1), two equivalent Ge(3), two equivalent Ge(4), and four equivalent Ge(2) atoms. There are four inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 8-coordinate geometry to four equivalent Sc(1), two equivalent Hf(1), and two equivalent Ge(2) atoms. In the second Ge site, Ge(2) is bonded in a 8-coordinate geometry to two equivalent Sc(1), four equivalent Hf(1), and two equivalent Ge(1) atoms. In the third Ge site, Ge(3) is bonded in a 8-coordinate geometry to two equivalent Sc(1), two equivalent Hf(1), and four equivalent Ge(4) atoms. In the fourth Ge site, Ge(4) is bonded in a 8-coordinate geometry to two equivalent Sc(1), two equivalent Hf(1), and four equivalent Ge(3) atoms.
