KAg2SbS4 crystallizes in the tetragonal I-42m space group. K(1) is bonded in a 4-coordinate geometry to four equivalent S(1) atoms. Ag(1) is bonded to four equivalent S(1) atoms to form distorted AgS4 trigonal pyramids that share corners with four equivalent Sb(1)S4 tetrahedra and corners with four equivalent Ag(1)S4 trigonal pyramids. Sb(1) is bonded to four equivalent S(1) atoms to form SbS4 tetrahedra that share corners with eight equivalent Ag(1)S4 trigonal pyramids. S(1) is bonded in a 4-coordinate geometry to one K(1), two equivalent Ag(1), and one Sb(1) atom.
