BeNi2Ge crystallizes in the triclinic P1 space group. Be(1) is bonded in a 4-coordinate geometry to one Ni(1) and three equivalent Ni(2) atoms. The Be(1)-Ni(1) bond length is 2.04 Å. There are a spread of Be(1)-Ni(2) bond distances ranging from 1.63-2.65 Å. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 3-coordinate geometry to one Be(1) and two equivalent Ge(1) atoms. There is one shorter (1.50 Å) and one longer (2.06 Å) Ni(1)-Ge(1) bond length. In the second Ni site, Ni(2) is bonded in a 4-coordinate geometry to three equivalent Be(1) and one Ge(1) atom. The Ni(2)-Ge(1) bond length is 1.66 Å. Ge(1) is bonded in a 3-coordinate geometry to one Ni(2) and two equivalent Ni(1) atoms.
