Materials Data on MnGeP2 by Materials Project
MnGeP2 is Chalcopyrite structured and crystallizes in the tetragonal I-42d space group. The structure is three-dimensional. Mn2+ is bonded to four equivalent P3- atoms to form MnP4 tetrahedra that share corners with four equivalent MnP4 tetrahedra and corners with eight equivalent GeP4 tetrahedra. All Mn–P bond lengths are 2.30 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 MnP4 tetrahedra. All Ge–P bond lengths are 2.40 Å. P3- is bonded to two equivalent Mn2+ and two equivalent Ge4+ atoms to form corner-sharing PMn2Ge2 tetrahedra.
