Abstract

AgGdS2 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. there are four inequivalent Gd3+ sites. In the first Gd3+ site, Gd3+ is bonded to six S2- atoms to form GdS6 octahedra that share corners with four equivalent GdS6 octahedra, corners with three AgS5 trigonal bipyramids, edges with four GdS6 octahedra, and edges with six AgS5 trigonal bipyramids. The corner-sharing octahedra tilt angles range from 18–23°. There are a spread of Gd–S bond distances ranging from 2.76–2.80 Å. In the second Gd3+ site, Gd3+ is bonded to six S2- atoms to form GdS6 octahedra that share corners with four equivalent GdS6 octahedra, corners with three AgS5 trigonal bipyramids, edges with four GdS6 octahedra, and edges with six AgS5 trigonal bipyramids.
