YbS2 crystallizes in the monoclinic C2/c space group. Yb(1) is bonded to eight equivalent S(1) atoms to form a mixture of corner and edge-sharing YbS8 hexagonal bipyramids. S(1) is bonded in a 5-coordinate geometry to four equivalent Yb(1) and one S(1) atom.
YbS2 crystallizes in the monoclinic C2/c space group. Yb(1) is bonded to eight equivalent S(1) atoms to form a mixture of corner and edge-sharing YbS8 hexagonal bipyramids. There are a spread of Yb(1)-S(1) bond distances ranging from 2.83-2.90 Å. S(1) is bonded in a 5-coordinate geometry to four equivalent Yb(1) and one S(1) atom. The S(1)-S(1) bond length is 2.10 Å.
