Yb2S3 is Corundum structured and crystallizes in the trigonal R-3c space group. Yb(1) is bonded to six equivalent S(1) atoms to form a mixture of face, corner, and edge-sharing YbS6 octahedra. The corner-sharing octahedral tilt angles range from 44-62°. S(1) is bonded in a distorted see-saw-like geometry to four equivalent Yb(1) atoms.

The corner-sharing octahedral tilt angles range from 44-62°. There are three shorter (2.79 Å) and three longer (2.80 Å) Yb(1)-S(1) bond lengths. S(1) is bonded in a distorted see-saw-like geometry to four equivalent Yb(1) atoms.
