Materials Data on Ge2Mo by Materials Project
MoGe2 is Cotunnite structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Mo is bonded in a 9-coordinate geometry to nine Ge atoms. There are a spread of Mo–Ge bond distances ranging from 2.60–2.90 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 4-coordinate geometry to five equivalent Mo and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.73 Å. In the second Ge site, Ge is bonded in a 8-coordinate geometry to four equivalent Mo and four Ge atoms. Both Ge–Ge bond lengths are 2.56 Å.
