The compound described by NbMnGe crystallizes in the hexagonal P-62m space group. Nb(1) is bonded in a 5-coordinate geometry to one Ge(2) and four equivalent Ge(1) atoms. Mn(1) is bonded in a 4-coordinate geometry to two equivalent Ge(1) and two equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(2) is bonded in a 9-coordinate geometry to three equivalent Nb(1) and six equivalent Mn(1) atoms. In the second Ge site, Ge(1) is bonded in a 9-coordinate geometry to six equivalent Nb(1) and three equivalent Mn(1) atoms. is represented by the CIF file [CIF]
