Abstract

Pr3NSe3 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are three inequivalent Pr3+ sites. In the first Pr3+ site, Pr3+ is bonded in a 1-coordinate geometry to one N3- and six Se2- atoms. The Pr–N bond length is 2.35 Å. There are a spread of Pr–Se bond distances ranging from 2.97–3.33 Å. In the second Pr3+ site, Pr3+ is bonded to one N3- and five Se2- atoms to form distorted edge-sharing PrSe5N octahedra. The Pr–N bond length is 2.30 Å. There are four shorter (3.00 Å) and one longer (3.24 Å) Pr–Se bond lengths. In the third Pr3+ site, Pr3+ is bonded in a 2-coordinate geometry to two equivalent N3- and five Se2- atoms. Both Pr–N bond lengths are 2.45 Å. There are a spread of Pr–Se bond distances ranging from 3.03–3.30 Å. N3- is bonded to four Pr3+ atoms to form NPr4 tetrahedra that share corners with three equivalent SePr6 octahedra, corners with two equivalent SePr5 square pyramids, corners with two equivalent NPr4 tetrahedra, edges with two equivalent SePr6 octahedra, and edges with three equivalent SePr5 square pyramids. The corner-sharing octahedra tilt angles range from 9–41°. There are three inequivalent Se2- sites. In the firstmore »« less
