The material described by PrNiGe3 crystallizes in the orthorhombic Cmmm space group. Pr(1) is bonded in a 14-coordinate geometry to four equivalent Ni(1), two equivalent Ge(1), two equivalent Ge(2), and six equivalent Ge(3) atoms. Ni(1) is bonded in a 9-coordinate geometry to four equivalent Pr(1), one Ge(3), two equivalent Ge(1), and two equivalent Ge(2) atoms. There are three inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to two equivalent Pr(1), two equivalent Ni(1), one Ge(1), and four equivalent Ge(2) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to two equivalent Pr(1), two equivalent Ni(1), one Ge(2), and four equivalent Ge(1) atoms. In the third Ge site, Ge(3) is bonded in a 9-coordinate geometry to six equivalent Pr(1), one Ni(1), and two equivalent Ge(3) atoms. is represented by the CIF card [CIF]
