Abstract

AgSb(PbS2)2 is Caswellsilverite-derived structured and crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Ag1+ is bonded to six S2- atoms to form AgS6 octahedra that share corners with two equivalent SbS6 octahedra, corners with four equivalent AgS6 octahedra, edges with four equivalent SbS6 octahedra, and edges with eight equivalent PbS6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are four shorter (2.87 Å) and two longer (3.33 Å) Ag–S bond lengths. Pb2+ is bonded to six S2- atoms to form PbS6 octahedra that share corners with six equivalent PbS6 octahedra, edges with four equivalent AgS6 octahedra, edges with four equivalent PbS6 octahedra, and edges with four equivalent SbS6 octahedra. The corner-sharing octahedra tilt angles range from 0–12°. There are four shorter (2.89 Å) and two longer (3.02 Å) Pb–S bond lengths. Sb3+ is bonded to six S2- atoms to form SbS6 octahedra that share corners with two equivalent AgS6 octahedra, corners with four equivalent SbS6 octahedra, edges with four equivalent AgS6 octahedra, and edges with eight equivalent PbS6 octahedra. The corner-sharing octahedral tilt angles are 0°. There are two shorter (2.71 Å) and four longer (2.87 Å) Sb–S bond lengths. There are three inequivalent S2- sites.more »« less
