The compound described by Nd5Ge3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Nd sites. In the first Nd site, Nd(1) is bonded in a 5-coordinate geometry to five equivalent Ge(1) atoms. In the second Nd site, Nd(2) is bonded in a distorted trigonal planar geometry to three equivalent Ge(1) atoms. Ge(1) is bonded to two equivalent Nd(2) and five equivalent Nd(1) atoms to form a mixture of distorted corner and edge-sharing GeNd7 hexagonal pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
