Abstract

TbCuPbSe3 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Tb3+ is bonded to six Se2- atoms to form TbSe6 octahedra that share corners with two equivalent TbSe6 octahedra, corners with six equivalent PbSe7 pentagonal bipyramids, edges with two equivalent TbSe6 octahedra, edges with four equivalent PbSe7 pentagonal bipyramids, and edges with four equivalent CuSe4 tetrahedra. The corner-sharing octahedral tilt angles are 44°. There are a spread of Tb–Se bond distances ranging from 2.87–2.91 Å. Cu1+ is bonded to four Se2- atoms to form CuSe4 tetrahedra that share corners with three equivalent PbSe7 pentagonal bipyramids, corners with two equivalent CuSe4 tetrahedra, edges with four equivalent TbSe6 octahedra, and edges with three equivalent PbSe7 pentagonal bipyramids. There are a spread of Cu–Se bond distances ranging from 2.44–2.52 Å. Pb2+ is bonded to seven Se2- atoms to form distorted PbSe7 pentagonal bipyramids that share corners with six equivalent TbSe6 octahedra, corners with three equivalent CuSe4 tetrahedra, edges with four equivalent TbSe6 octahedra, edges with two equivalent PbSe7 pentagonal bipyramids, edges with three equivalent CuSe4 tetrahedra, and faces with two equivalent PbSe7 pentagonal bipyramids.
