Materials Data on AgWS4N by Materials Project

(WAgS4)2N2 is I4/mcm-derived structured and crystallizes in the tetragonal I-4 space group. The structure is one-dimensional and consists of two ammonia molecules and two WAgS4 ribbons oriented in the (0, 0, 1) direction. In each WAgS4 ribbon, W6+ is bonded to four equivalent S2- atoms to form WS4 tetrahedra that share edges with two equivalent AgS4 tetrahedra. All W–S bond lengths are 2.22 Å. Ag1+ is bonded to four equivalent S2- atoms to form distorted AgS4 tetrahedra that share edges with two equivalent WS4 tetrahedra. All Ag–S bond lengths are 2.51 Å. S2- is bonded in a distorted L-shaped geometry to one W6+ and one Ag1+ atom.
