USeTe crystallizes in the orthorhombic Pnma space group. U(1) is bonded in a 9-coordinate geometry to five equivalent Te(1) and four equivalent Se(1) atoms. Te(1) is bonded to five equivalent U(1) atoms to form distorted TeU5 trigonal bipyramids that share corners with eight equivalent Se(1)U4 tetrahedra, corners with eight equivalent Te(1)U5 trigonal bipyramids, edges with six equivalent Se(1)U4 tetrahedra, and edges with six equivalent Te(1)U5 trigonal bipyramids. Se(1) is bonded to four equivalent U(1) atoms to form SeU4 tetrahedra that share corners with eight equivalent Se(1)U4 tetrahedra, corners with eight equivalent Te(1)U5 trigonal bipyramids, edges with two equivalent Se(1)U4 tetrahedra, and edges with six equivalent Te(1)U5 trigonal bipyramids.
USeTe crystallizes in the orthorhombic Pnma space group. U(1) is bonded in a 9-coordinate geometry to five equivalent Te(1) and four equivalent Se(1) atoms. There are four shorter (3.29 Å) and one longer (3.33 Å) U(1)-Te(1) bond length. There are a spread of U(1)-Se(1) bond distances ranging from 2.92-2.99 Å. Te(1) is bonded to five equivalent U(1) atoms to form distorted TeU5 trigonal bipyramids that share corners with eight equivalent Se(1)U4 tetrahedra, corners with eight equivalent Te(1)U5 trigonal bipyramids, edges with six equivalent Se(1)U4 tetrahedra, and edges with six equivalent Te(1)U5 trigonal bipyramids. Se(1) is bonded to four equivalent U(1) atoms to form SeU4 tetrahedra that share corners with eight equivalent Se(1)U4 tetrahedra, corners with eight equivalent Te(1)U5 trigonal bipyramids, edges with two equivalent Se(1)U4 tetrahedra, and edges with six equivalent Te(1)U5 trigonal bipyramids.
