Materials Data on AsPdS by Materials Project
PdAsS crystallizes in the cubic P2_13 space group. The structure is three-dimensional. Pd4+ is bonded to three equivalent As2- and three equivalent S2- atoms to form PdAs3S3 octahedra that share corners with twelve equivalent PdAs3S3 octahedra, corners with three equivalent AsPd3S tetrahedra, and corners with three equivalent SAsPd3 tetrahedra. The corner-sharing octahedra tilt angles range from 65–66°. All Pd–As bond lengths are 2.53 Å. All Pd–S bond lengths are 2.54 Å. As2- is bonded to three equivalent Pd4+ and one S2- atom to form distorted AsPd3S tetrahedra that share corners with three equivalent PdAs3S3 octahedra, corners with six equivalent AsPd3S tetrahedra, and corners with nine equivalent SAsPd3 tetrahedra. The corner-sharing octahedral tilt angles are 76°. The As–S bond length is 2.29 Å. S2- is bonded to three equivalent Pd4+ and one As2- atom to form SAsPd3 tetrahedra that share corners with three equivalent PdAs3S3 octahedra, corners with six equivalent SAsPd3 tetrahedra, and corners with nine equivalent AsPd3S tetrahedra. The corner-sharing octahedral tilt angles are 77°.
