The crystal structure described by K3RhCl6 crystallizes in the monoclinic P2_1/c space group. There are three inequivalent K sites. In the first K site, K(1) is bonded in a 9-coordinate geometry to one Cl(4), one Cl(5), two equivalent Cl(2), two equivalent Cl(6), and three equivalent Cl(1) atoms. In the second K site, K(2) is bonded in a 8-coordinate geometry to one Cl(1), one Cl(2), one Cl(5), one Cl(6), two equivalent Cl(3), and two equivalent Cl(4) atoms. In the third K site, K(3) is bonded in a 8-coordinate geometry to one Cl(1), one Cl(2), one Cl(4), one Cl(6), two equivalent Cl(3), and two equivalent Cl(5) atoms. There are two inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in an octahedral geometry to two equivalent Cl(1), two equivalent Cl(2), and two equivalent Cl(6) atoms. In the second Rh site, Rh(2) is bonded in an octahedral geometry to two equivalent Cl(3), two equivalent Cl(4), and two equivalent Cl(5) atoms. There are six inequivalent Cl sites. In the first Cl site, Cl(6) is bonded to one K(2), one K(3), two equivalent K(1), and one Rh(1) atom to form a mixture of distorted edge, face, and corner-sharing ClK4Rh square pyramids. In the second Cl site, Cl(1) is bonded in a 6-coordinate geometry to one K(2), one K(3), three equivalent K(1), and one Rh(1) atom. In the third Cl site, Cl(2) is bonded to one K(2), one K(3), two equivalent K(1), and one Rh(1) atom to form a mixture of distorted edge, face, and corner-sharing ClK4Rh square pyramids. In the fourth Cl site, Cl(3) is bonded to two equivalent K(2), two equivalent K(3), and one Rh(2) atom to form a mixture of distorted edge and corner-sharing ClK4Rh trigonal bipyramids. In the fifth Cl site, Cl(4) is bonded in a 5-coordinate geometry to one K(1), one K(3), two equivalent K(2), and one Rh(2) atom. In the sixth Cl site, Cl(5) is bonded in a 5-coordinate geometry to one K(1), one K(2), two equivalent K(3), and one Rh(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
