Materials Data on ZnGeP2 by Materials Project

ZnGeP2 is Chalcopyrite structured and crystallizes in the tetragonal I-42d space group. The structure is three-dimensional. Zn2+ is bonded to four equivalent P3- atoms to form ZnP4 tetrahedra that share corners with four equivalent ZnP4 tetrahedra and corners with eight equivalent GeP4 tetrahedra. All Zn–P bond lengths are 2.38 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 ZnP4 tetrahedra. All Ge–P bond lengths are 2.36 Å. P3- is bonded to two equivalent Zn2+ and two equivalent Ge4+ atoms to form corner-sharing PZn2Ge2 tetrahedra.

Materials Data on ZnGeP2 by Materials Project

ZnGeP2 is Chalcopyrite-like structured and crystallizes in the tetragonal P-4m2 space group. The structure is three-dimensional. Zn2+ is bonded to four equivalent P3- atoms to form ZnP4 tetrahedra that share corners with four equivalent ZnP4 tetrahedra and corners with eight equivalent GeP4 tetrahedra. All Zn–P bond lengths are 2.35 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 ZnP4 tetrahedra. All Ge–P bond lengths are 2.38 Å. P3- is bonded to two equivalent Zn2+ and two equivalent Ge4+ atoms to form corner-sharing PZn2Ge2 tetrahedra.
