The compound described by Rb2NbAgS4 crystallizes in the orthorhombic Fddd space group. Rb(1) is bonded in a 8-coordinate geometry to eight equivalent S(1) atoms. Nb(1) is bonded to four equivalent S(1) atoms to form NbS4 tetrahedra that share edges with two equivalent Ag(1)S4 tetrahedra. Ag(1) is bonded to four equivalent S(1) atoms to form distorted AgS4 tetrahedra that share edges with two equivalent Nb(1)S4 tetrahedra. S(1) is bonded in a 6-coordinate geometry to four equivalent Rb(1), one Nb(1), and one Ag(1) atom. is represented by the CIF card [CIF]
