Abstract

SrCrCu3Se4 crystallizes in the triclinic P1 space group. The structure is three-dimensional. Sr2+ is bonded to four Se2- atoms to form SrSe4 tetrahedra that share corners with four equivalent CrSe4 tetrahedra and corners with twelve CuSe4 tetrahedra. There are two shorter (2.86 Å) and two longer (2.87 Å) Sr–Se bond lengths. Cr3+ is bonded to four Se2- atoms to form CrSe4 tetrahedra that share corners with four equivalent SrSe4 tetrahedra and edges with six CuSe4 tetrahedra. All Cr–Se bond lengths are 2.36 Å. There are three inequivalent Cu1+ sites. In the first Cu1+ site, Cu1+ is bonded to four Se2- atoms to form CuSe4 tetrahedra that share corners with four equivalent SrSe4 tetrahedra, corners with eight CuSe4 tetrahedra, and edges with two equivalent CrSe4 tetrahedra. All Cu–Se bond lengths are 2.54 Å. In the second Cu1+ site, Cu1+ is bonded to four Se2- atoms to form CuSe4 tetrahedra that share corners with four equivalent SrSe4 tetrahedra, corners with eight CuSe4 tetrahedra, and edges with two equivalent CrSe4 tetrahedra. All Cu–Se bond lengths are 2.54 Å. In the third Cu1+ site, Cu1+ is bonded to four Se2- atoms to form CuSe4 tetrahedra that share corners with four equivalent SrSe4 tetrahedra, cornersmore »« less
