Description
A new compound Mg7Ga2GeO12, has been identified in the MgO-Ga2O3-GeO2 system (at 1 atmosphere pressure). Its unit cell is orthorhombic with parameters a=5.8493(5), b=25.449(3) and c=2.9816(3) A, with V=443.8 A3, Z=2, Dx=4.30 g cm-3 and Mr=574.2. A structural model, determined from powder X-ray diffraction data, shows that it is isostructural with Fe9PO12. Its crystal structure is simply related to that of the spinelloid phases and, like them, can be described as an intergrowth of the rock salt and β-Ga2O3 types. (orig.)
