The structure described by Nd2RuGe2 crystallizes in the monoclinic C2/m space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 10-coordinate geometry to four equivalent Ru(1), two equivalent Ge(2), and four equivalent Ge(1) atoms. In the second Nd site, Nd(2) is bonded in a 8-coordinate geometry to two equivalent Ru(1), one Ge(1), and five equivalent Ge(2) atoms. Ru(1) is bonded in a 10-coordinate geometry to two equivalent Nd(2), four equivalent Nd(1), one Ge(2), and three equivalent Ge(1) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 8-coordinate geometry to one Nd(2), four equivalent Nd(1), and three equivalent Ru(1) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to two equivalent Nd(1), five equivalent Nd(2), one Ru(1), and one Ge(2) atom. is represented by the CIF file [CIF]
