EuMoOs2 crystallizes in the trigonal R3m space group. Eu(1) is bonded in a 10-coordinate geometry to four equivalent Mo(1), three equivalent Os(1), and three equivalent Os(2) atoms. There is one shorter (2.44 Å) and three longer (2.92 Å) Eu(1)-Mo(1) bond lengths. All Eu(1)-Os(1) bond lengths are 2.70 Å. All Eu(1)-Os(2) bond lengths are 2.70 Å. Mo(1) is bonded in a distorted linear geometry to four equivalent Eu(1) and one Os(2) atom. The Mo(1)-Os(2) bond length is 1.92 Å. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded in a 3-coordinate geometry to three equivalent Eu(1) and one Os(2) atom. The Os(1)-Os(2) bond length is 2.44 Å. In the second Os site, Os(2) is bonded in a 5-coordinate geometry to three equivalent Eu(1), one Mo(1), and one Os(1) atom.
