摘要：

A new high-pressure polymorph with a modified spinel structure, β-Mn2GeO4, is stable in a pressure range intermediate between the field of the polymorph with the olivine structure and that of another high-pressure polymorph. Oxygen atoms are located approximately in cubic close packing with manganese and germanium atoms in octahedral and tetrahedral interstices, respectively, as in the spinel structure; however, germanium atoms form Ge2O7 groups instead of isolated GeO4 groups.
