The compound described by EuS2 crystallizes in the monoclinic P2_1/c space group. Eu(1) is bonded in a 9-coordinate geometry to four equivalent S(1) and five equivalent S(2) atoms. There are two inequivalent S sites. In the first S site, S(2) is bonded to five equivalent Eu(1) atoms to form a mixture of corner and edge-sharing SEu5 square pyramids. In the second S site, S(1) is bonded in a distorted pentagonal planar geometry to four equivalent Eu(1) and one S(1) atom. is represented by the CIF card [CIF]
