Materials Data on KSbS2 by Materials Project
KSbS2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. K1+ is bonded to six equivalent S2- atoms to form a mixture of distorted edge and corner-sharing KS6 octahedra. The corner-sharing octahedral tilt angles are 16°. There are two shorter (3.27 Å) and four longer (3.28 Å) K–S bond lengths. Sb3+ is bonded in a see-saw-like geometry to four equivalent S2- atoms. There are two shorter (2.46 Å) and two longer (2.79 Å) Sb–S bond lengths. S2- is bonded to three equivalent K1+ and two equivalent Sb3+ atoms to form a mixture of edge and corner-sharing SK3Sb2 square pyramids.
