Y6RhI10 crystallizes in the triclinic P-1 space group. There are three inequivalent Y sites. In the first Y site, Y(1) is bonded to one Rh(1), one I(1), one I(3), one I(4), and two equivalent I(5) atoms to form a mixture of distorted corner and edge-sharing YRhI5 octahedra. The corner-sharing octahedral tilt angles range from 0-11°. In the second Y site, Y(2) is bonded to one Rh(1), one I(1), one I(2), one I(3), and two equivalent I(4) atoms to form a mixture of corner and edge-sharing YRhI5 octahedra. The corner-sharing octahedral tilt angles range from 0-7°. In the third Y site, Y(3) is bonded to one Rh(1), one I(3), one I(4), one I(5), and two equivalent I(2) atoms to form a mixture of corner and edge-sharing YRhI5 octahedra. The corner-sharing octahedral tilt angles range from 0-11°. Rh(1) is bonded in an octahedral geometry to two equivalent Y(1), two equivalent Y(2), and two equivalent Y(3) atoms. There are five inequivalent I sites. In the first I site, I(1) is bonded in a distorted L-shaped geometry to one Y(1) and one Y(2) atom. In the second I site, I(2) is bonded in a distorted T-shaped geometry to one Y(2) and two equivalent Y(3) atoms. In the third I site, I(3) is bonded in a distorted T-shaped geometry to one Y(1), one Y(2), and one Y(3) atom. In the fourth I site, I(4) is bonded in a rectangular see-saw-like geometry to one Y(1), one Y(3), and two equivalent Y(2) atoms. In the fifth I site, I(5) is bonded in a distorted T-shaped geometry to one Y(3) and two equivalent Y(1) atoms.
