Materials Data on Yb(PPd)2 by Materials Project

YbPd2P2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Yb2+ is bonded to eight equivalent P3- atoms to form YbP8 hexagonal bipyramids that share corners with sixteen equivalent PdP4 tetrahedra, edges with four equivalent YbP8 hexagonal bipyramids, edges with eight equivalent PdP4 tetrahedra, and faces with four equivalent YbP8 hexagonal bipyramids. All Yb–P bond lengths are 3.12 Å. Pd2+ is bonded to four equivalent P3- atoms to form PdP4 tetrahedra that share corners with eight equivalent YbP8 hexagonal bipyramids, corners with four equivalent PdP4 tetrahedra, edges with four equivalent YbP8 hexagonal bipyramids, and edges with four equivalent PdP4 tetrahedra. All Pd–P bond lengths are 2.47 Å. P3- is bonded in a 9-coordinate geometry to four equivalent Yb2+, four equivalent Pd2+, and one P3- atom. The P–P bond length is 2.16 Å.
