NiInGe2 crystallizes in the triclinic P1 space group. Ni(1) is bonded in a 1-coordinate geometry to one In(1), one Ge(1), and one Ge(2) atom. The Ni(1)-In(1) bond length is 2.99 Å. The Ni(1)-Ge(1) bond length is 2.12 Å. The Ni(1)-Ge(2) bond length is 1.03 Å. In(1) is bonded in a 6-coordinate geometry to one Ni(1), two equivalent In(1), one Ge(2), and two equivalent Ge(1) atoms. Both In(1)-In(1) bond lengths are 2.88 Å. The In(1)-Ge(2) bond length is 2.60 Å. There is one shorter (2.39 Å) and one longer (2.72 Å) In(1)-Ge(1) bond length. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 3-coordinate geometry to one Ni(1) and two equivalent In(1) atoms. In the second Ge site, Ge(2) is bonded in a 1-coordinate geometry to one Ni(1) and one In(1) atom.
