The material described by Nd3Ge5 crystallizes in the monoclinic C2 space group. There are four inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 10-coordinate geometry to one Ge(2), one Ge(4), one Ge(5), one Ge(6), three equivalent Ge(1), and three equivalent Ge(3) atoms. In the second Nd site, Nd(2) is bonded in a 10-coordinate geometry to one Ge(1), one Ge(3), one Ge(4), one Ge(5), three equivalent Ge(2), and three equivalent Ge(6) atoms. In the third Nd site, Nd(3) is bonded in a 10-coordinate geometry to two equivalent Ge(1), two equivalent Ge(2), two equivalent Ge(3), two equivalent Ge(5), and two equivalent Ge(6) atoms. In the fourth Nd site, Nd(4) is bonded in a 10-coordinate geometry to two equivalent Ge(1), two equivalent Ge(2), two equivalent Ge(3), two equivalent Ge(4), and two equivalent Ge(6) atoms. There are six inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to one Nd(2), one Nd(3), one Nd(4), three equivalent Nd(1), one Ge(3), one Ge(5), and one Ge(6) atom. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to one Nd(1), one Nd(3), one Nd(4), three equivalent Nd(2), one Ge(3), one Ge(4), and one Ge(6) atom. In the third Ge site, Ge(3) is bonded in a 8-coordinate geometry to one Nd(2), one Nd(3), one Nd(4), three equivalent Nd(1), one Ge(1), and one Ge(2) atom. In the fourth Ge site, Ge(4) is bonded in a 8-coordinate geometry to two equivalent Nd(1), two equivalent Nd(2), two equivalent Nd(4), and two equivalent Ge(2) atoms. In the fifth Ge site, Ge(5) is bonded in a 8-coordinate geometry to two equivalent Nd(1), two equivalent Nd(2), two equivalent Nd(3), and two equivalent Ge(1) atoms. In the sixth Ge site, Ge(6) is bonded in a 8-coordinate geometry to one Nd(1), one Nd(3), one Nd(4), three equivalent Nd(2), one Ge(1), and one Ge(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
