YbLaS3 crystallizes in the orthorhombic Pna2_1 space group. Yb(1) is bonded to two equivalent S(1), two equivalent S(2), and two equivalent S(3) atoms to form corner-sharing YbS6 octahedra. The corner-sharing octahedral tilt angles range from 40-68°. La(1) is bonded in a 8-coordinate geometry to two equivalent S(3), three equivalent S(1), and three equivalent S(2) atoms. There are three inequivalent S sites. In the first S site, S(1) is bonded in a 5-coordinate geometry to two equivalent Yb(1) and three equivalent La(1) atoms. In the second S site, S(2) is bonded in a 5-coordinate geometry to two equivalent Yb(1) and three equivalent La(1) atoms. In the third S site, S(3) is bonded in a see-saw-like geometry to two equivalent Yb(1) and two equivalent La(1) atoms.
