The material structure described by Pr2NiGe6 crystallizes in the orthorhombic Amm2 space group. There are two inequivalent Pr sites. In the first Pr site, Pr(1) is bonded in a 10-coordinate geometry to two equivalent Ge(2), two equivalent Ge(4), two equivalent Ge(5), and four equivalent Ge(6) atoms. In the second Pr site, Pr(2) is bonded in a 14-coordinate geometry to four equivalent Ni(1), two equivalent Ge(1), two equivalent Ge(3), two equivalent Ge(6), and four equivalent Ge(5) atoms. Ni(1) is bonded in a 9-coordinate geometry to four equivalent Pr(2), one Ge(5), two equivalent Ge(1), and two equivalent Ge(3) atoms. There are six inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to two equivalent Pr(2), two equivalent Ni(1), one Ge(2), and four equivalent Ge(3) atoms. In the second Ge site, Ge(2) is bonded in a 7-coordinate geometry to two equivalent Pr(1), one Ge(1), and four equivalent Ge(4) atoms. In the third Ge site, Ge(3) is bonded in a 9-coordinate geometry to two equivalent Pr(2), two equivalent Ni(1), one Ge(4), and four equivalent Ge(1) atoms. In the fourth Ge site, Ge(4) is bonded in a 7-coordinate geometry to two equivalent Pr(1), one Ge(3), and four equivalent Ge(2) atoms. In the fifth Ge site, Ge(5) is bonded in a 9-coordinate geometry to two equivalent Pr(1), four equivalent Pr(2), one Ni(1), and two equivalent Ge(6) atoms. In the sixth Ge site, Ge(6) is bonded in a 8-coordinate geometry to two equivalent Pr(2), four equivalent Pr(1), and two equivalent Ge(5) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
