Materials Data on AlPS4 by Materials Project
AlPS4 is Silicon Disuphide-derived structured and crystallizes in the orthorhombic P222 space group. The structure is one-dimensional and consists of two AlPS4 ribbons oriented in the (0, 1, 0) direction. Al3+ is bonded to four equivalent S2- atoms to form distorted AlS4 tetrahedra that share edges with two equivalent PS4 tetrahedra. All Al–S bond lengths are 2.27 Å. P5+ is bonded to four equivalent S2- atoms to form PS4 tetrahedra that share edges with two equivalent AlS4 tetrahedra. All P–S bond lengths are 2.07 Å. S2- is bonded in an L-shaped geometry to one Al3+ and one P5+ atom.
