Abstract

Li2PrAs2 crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. Li1+ is bonded to four equivalent As+2.50- atoms to form LiAs4 tetrahedra that share corners with six equivalent PrAs6 octahedra, corners with six equivalent LiAs4 tetrahedra, edges with three equivalent PrAs6 octahedra, and edges with three equivalent LiAs4 tetrahedra. The corner-sharing octahedra tilt angles range from 14–55°. There are three shorter (2.65 Å) and one longer (2.67 Å) Li–As bond lengths. Pr3+ is bonded to six equivalent As+2.50- atoms to form PrAs6 octahedra that share corners with twelve equivalent LiAs4 tetrahedra, edges with six equivalent PrAs6 octahedra, and edges with six equivalent LiAs4 tetrahedra. All Pr–As bond lengths are 3.03 Å. As+2.50- is bonded to four equivalent Li1+ and three equivalent Pr3+ atoms to form a mixture of distorted edge and corner-sharing AsLi4Pr3 pentagonal bipyramids.
