Materials Data on MgGeP2 by Materials Project

MgGeP2 is Chalcopyrite structured and crystallizes in the tetragonal I-42d space group. The structure is three-dimensional. Mg2+ is bonded to four equivalent P3- atoms to form MgP4 tetrahedra that share corners with four equivalent MgP4 tetrahedra and corners with eight equivalent GeP4 tetrahedra. All Mg–P bond lengths are 2.55 Å. Ge4+ is bonded to four equivalent P3- atoms to form GeP4 tetrahedra that share corners with four equivalent GeP4 tetrahedra and corners with eight equivalent MgP4 tetrahedra. All Ge–P bond lengths are 2.36 Å. P3- is bonded to two equivalent Mg2+ and two equivalent Ge4+ atoms to form corner-sharing PMg2Ge2 tetrahedra.
