EuMo6S8 crystallizes in the triclinic P-1 space group. Eu(1) is bonded in a 2-coordinate geometry to two equivalent S(2), two equivalent S(3), and two equivalent S(4) atoms. There are three inequivalent Mo sites. In the first Mo site, Mo(1) is bonded in a 4-coordinate geometry to one S(1), one S(2), one S(3), and one S(4) atom. In the second Mo site, Mo(2) is bonded in a 3-coordinate geometry to one S(1), one S(2), and one S(3) atom. In the third Mo site, Mo(3) is bonded in a 3-coordinate geometry to one S(1), one S(3), and one S(4) atom. There are four inequivalent S sites. In the first S site, S(1) is bonded in a distorted trigonal non-coplanar geometry to one Mo(1), one Mo(2), and one Mo(3) atom. In the second S site, S(2) is bonded in a 3-coordinate geometry to one Eu(1), one Mo(1), and one Mo(2) atom. In the third S site, S(3) is bonded in a 4-coordinate geometry to one Eu(1), one Mo(1), one Mo(2), and one Mo(3) atom. In the fourth S site, S(4) is bonded in a 3-coordinate geometry to one Eu(1), one Mo(1), and one Mo(3) atom.
