PrSI is Baddeleyite-derived structured and crystallizes in the orthorhombic Pbca space group. Pr(1) is bonded in a 7-coordinate geometry to four equivalent S(1) and three equivalent I(1) atoms. S(1) is bonded to four equivalent Pr(1) atoms to form a mixture of corner and edge-sharing SPr4 tetrahedra. I(1) is bonded in a distorted trigonal planar geometry to three equivalent Pr(1) atoms.
PrSI is Baddeleyite-derived structured and crystallizes in the orthorhombic Pbca space group. Pr(1) is bonded in a 7-coordinate geometry to four equivalent S(1) and three equivalent I(1) atoms. There are three shorter (2.86 Å) and one longer (2.87 Å) Pr(1)-S(1) bond length. There are a spread of Pr(1)-I(1) bond distances ranging from 3.28-3.48 Å. S(1) is bonded to four equivalent Pr(1) atoms to form a mixture of corner and edge-sharing SPr4 tetrahedra. I(1) is bonded in a distorted trigonal planar geometry to three equivalent Pr(1) atoms.
