Ni6Ge2B crystallizes in the hexagonal P-62m space group. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 4-coordinate geometry to two equivalent B(1) and two equivalent Ge(1) atoms. In the second Ni site, Ni(2) is bonded in a 5-coordinate geometry to one B(1) and four equivalent Ge(1) atoms. B(1) is bonded in a 9-coordinate geometry to three equivalent Ni(2) and six equivalent Ni(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to three equivalent Ni(1) and six equivalent Ni(2) atoms.
Ni6Ge2B crystallizes in the hexagonal P-62m space group. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 4-coordinate geometry to two equivalent B(1) and two equivalent Ge(1) atoms. Both Ni(1)-B(1) bond lengths are 2.07 Å. Both Ni(1)-Ge(1) bond lengths are 2.40 Å. In the second Ni site, Ni(2) is bonded in a 5-coordinate geometry to one B(1) and four equivalent Ge(1) atoms. The Ni(2)-B(1) bond length is 2.34 Å. All Ni(2)-Ge(1) bond lengths are 2.41 Å. B(1) is bonded in a 9-coordinate geometry to three equivalent Ni(2) and six equivalent Ni(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to three equivalent Ni(1) and six equivalent Ni(2) atoms.
