Abstract

CrAgSnSe4 is Spinel-derived structured and crystallizes in the orthorhombic Imma space group. The structure is three-dimensional. Cr3+ is bonded to six Se2- atoms to form CrSe6 octahedra that share corners with six equivalent AgSe4 tetrahedra, edges with two equivalent CrSe6 octahedra, and edges with four equivalent SnSe6 octahedra. There are two shorter (2.55 Å) and four longer (2.59 Å) Cr–Se bond lengths. Ag1+ is bonded to four Se2- atoms to form AgSe4 tetrahedra that share corners with six equivalent CrSe6 octahedra and corners with six equivalent SnSe6 octahedra. The corner-sharing octahedra tilt angles range from 51–66°. There are two shorter (2.63 Å) and two longer (2.64 Å) Ag–Se bond lengths. Sn4+ is bonded to six Se2- atoms to form SnSe6 octahedra that share corners with six equivalent AgSe4 tetrahedra, edges with two equivalent SnSe6 octahedra, and edges with four equivalent CrSe6 octahedra. All Sn–Se bond lengths are 2.75 Å. There are two inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a rectangular see-saw-like geometry to one Cr3+, one Ag1+, and two equivalent Sn4+ atoms. In the second Se2- site, Se2- is bonded in a distorted rectangular see-saw-like geometry to two equivalent Cr3+, one Ag1+, and onemore » Sn4+ atom.« less
