Materials Data on CdGeP2 by Materials Project

CdGeP2 is Chalcopyrite structured and crystallizes in the tetragonal I-42d space group. The structure is three-dimensional. Cd2+ is bonded to four equivalent P3- atoms to form CdP4 tetrahedra that share corners with four equivalent CdP4 tetrahedra and corners with eight equivalent GeP4 tetrahedra. All Cd–P bond lengths are 2.59 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 CdP4 tetrahedra. All Ge–P bond lengths are 2.36 Å. P3- is bonded to two equivalent Cd2+ and two equivalent Ge4+ atoms to form corner-sharing PCd2Ge2 tetrahedra.
