Abstract

Pr3InSe6 crystallizes in the orthorhombic Pnnm space group. The structure is three-dimensional. there are three inequivalent Pr3+ sites. In the first Pr3+ site, Pr3+ is bonded to seven Se2- atoms to form distorted PrSe7 pentagonal bipyramids that share a cornercorner with one InSe6 octahedra, edges with two equivalent InSe6 octahedra, and edges with two equivalent PrSe7 pentagonal bipyramids. The corner-sharing octahedral tilt angles are 41°. There are a spread of Pr–Se bond distances ranging from 2.98–3.14 Å. In the second Pr3+ site, Pr3+ is bonded in a 8-coordinate geometry to eight Se2- atoms. There are a spread of Pr–Se bond distances ranging from 3.03–3.33 Å. In the third Pr3+ site, Pr3+ is bonded in a 8-coordinate geometry to eight Se2- atoms. There are a spread of Pr–Se bond distances ranging from 3.02–3.14 Å. There are two inequivalent In3+ sites. In the first In3+ site, In3+ is bonded to six Se2- atoms to form InSe6 octahedra that share corners with two equivalent PrSe7 pentagonal bipyramids and edges with two equivalent InSe6 octahedra. There are two shorter (2.61 Å) and four longer (2.92 Å) In–Se bond lengths. In the second In3+ site, In3+ is bonded to six Se2- atoms to form InSe6more »« less
