ZrCrGe2 crystallizes in the triclinic P1 space group. Zr(1) is bonded in a 7-coordinate geometry to three equivalent Cr(1), one Ge(1), and three equivalent Ge(2) atoms. There are a spread of Zr(1)-Cr(1) bond distances ranging from 2.48-3.66 Å. The Zr(1)-Ge(1) bond length is 2.69 Å. There are a spread of Zr(1)-Ge(2) bond distances ranging from 2.69-3.44 Å. Cr(1) is bonded in a distorted single-bond geometry to three equivalent Zr(1), one Ge(1), and one Ge(2) atom. The Cr(1)-Ge(1) bond length is 0.34 Å. The Cr(1)-Ge(2) bond length is 1.07 Å. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a single-bond geometry to one Zr(1) and one Cr(1) atom. In the second Ge site, Ge(2) is bonded in a distorted single-bond geometry to three equivalent Zr(1) and one Cr(1) atom.
