The crystal structure described by Pr6OsI10 crystallizes in the triclinic P-1 space group. There are three inequivalent Pr sites. In the first Pr site, Pr(1) is bonded to one Os(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 PrOsI5 octahedra. The corner-sharing octahedral tilt angles range from 0-10°. In the second Pr site, Pr(2) is bonded to one Os(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 PrOsI5 octahedra. The corner-sharing octahedral tilt angles range from 0-6°. In the third Pr site, Pr(3) is bonded to one Os(1), one I(3), one I(4), one I(5), and two equivalent I(2) atoms to form a mixture of distorted corner and edge-sharing PrOsI5 octahedra. The corner-sharing octahedral tilt angles range from 0-10°. Os(1) is bonded in an octahedral geometry to two equivalent Pr(1), two equivalent Pr(2), and two equivalent Pr(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 Pr(1) and one Pr(2) atom. In the second I site, I(2) is bonded in a T-shaped geometry to one Pr(2) and two equivalent Pr(3) atoms. In the third I site, I(3) is bonded in a distorted T-shaped geometry to one Pr(1), one Pr(2), and one Pr(3) atom. In the fourth I site, I(4) is bonded in a see-saw-like geometry to one Pr(1), one Pr(3), and two equivalent Pr(2) atoms. In the fifth I site, I(5) is bonded in a distorted T-shaped geometry to one Pr(3) and two equivalent Pr(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
