BaU(PS4)2 is Zircon-derived structured and crystallizes in the tetragonal P4_2/mbc space group. Ba(1) is bonded to four equivalent S(1) and four equivalent S(3) atoms to form distorted BaS8 hexagonal bipyramids that share edges with two equivalent Ba(1)S8 hexagonal bipyramids and edges with four equivalent P(1)S4 tetrahedra. U(1) is bonded in a 8-coordinate geometry to four equivalent S(1) and four equivalent S(2) atoms. P(1) is bonded to one S(2), one S(3), and two equivalent S(1) atoms to form PS4 tetrahedra that share edges with two equivalent Ba(1)S8 hexagonal bipyramids. There are three inequivalent S sites. In the first S site, S(2) is bonded in a 3-coordinate geometry to two equivalent U(1) and one P(1) atom. In the second S site, S(3) is bonded in a 3-coordinate geometry to two equivalent Ba(1) and one P(1) atom. In the third S site, S(1) is bonded in a distorted T-shaped geometry to one Ba(1), one U(1), and one P(1) atom.
