The structure described by Rb3YbCl6 crystallizes in the monoclinic C2/c space group. There are three inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 8-coordinate geometry to one Cl(1), one Cl(3), two equivalent Cl(2), two equivalent Cl(4), and two equivalent Cl(5) atoms. In the second Rb site, Rb(2) is bonded in a 8-coordinate geometry to one Cl(2), one Cl(3), one Cl(4), one Cl(5), two equivalent Cl(1), and two equivalent Cl(6) atoms. In the third Rb site, Rb(3) is bonded in a 8-coordinate geometry to one Cl(1), one Cl(2), one Cl(4), one Cl(5), two equivalent Cl(3), and two equivalent Cl(6) atoms. There are two inequivalent Yb sites. In the first Yb site, Yb(1) is bonded in an octahedral geometry to two equivalent Cl(2), two equivalent Cl(4), and two equivalent Cl(5) atoms. In the second Yb site, Yb(2) is bonded in an octahedral geometry to two equivalent Cl(1), two equivalent Cl(3), and two equivalent Cl(6) atoms. There are six inequivalent Cl sites. In the first Cl site, Cl(1) is bonded to one Rb(1), one Rb(3), two equivalent Rb(2), and one Yb(2) atom to form a mixture of distorted edge and corner-sharing ClRb4Yb trigonal bipyramids. In the second Cl site, Cl(2) is bonded to one Rb(2), one Rb(3), two equivalent Rb(1), and one Yb(1) atom to form a mixture of distorted edge and corner-sharing ClRb4Yb square pyramids. In the third Cl site, Cl(3) is bonded to one Rb(1), one Rb(2), two equivalent Rb(3), and one Yb(2) atom to form a mixture of distorted edge and corner-sharing ClRb4Yb trigonal bipyramids. In the fourth Cl site, Cl(4) is bonded to one Rb(2), one Rb(3), two equivalent Rb(1), and one Yb(1) atom to form a mixture of distorted edge, face, and corner-sharing ClRb4Yb square pyramids. In the fifth Cl site, Cl(5) is bonded in a 1-coordinate geometry to one Rb(2), one Rb(3), two equivalent Rb(1), and one Yb(1) atom. In the sixth Cl site, Cl(6) is bonded to two equivalent Rb(2), two equivalent Rb(3), and one Yb(2) atom to form a mixture of distorted edge and corner-sharing ClRb4Yb trigonal bipyramids. is represented by the CIF file [CIF]
