AgMo6Se8 crystallizes in the trigonal R-3 space group. Mo(1) is bonded to one Se(1) and four equivalent Se(2) atoms to form a mixture of distorted corner and edge-sharing MoSe5 square pyramids. Ag(1) is bonded in a distorted linear geometry to two equivalent Se(1) and six equivalent Se(2) atoms. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded in a 4-coordinate geometry to three equivalent Mo(1) and one Ag(1) atom. In the second Se site, Se(2) is bonded in a 5-coordinate geometry to four equivalent Mo(1) and one Ag(1) atom.
AgMo6Se8 crystallizes in the trigonal R-3 space group. Mo(1) is bonded to one Se(1) and four equivalent Se(2) atoms to form a mixture of distorted corner and edge-sharing MoSe5 square pyramids. The Mo(1)-Se(1) bond length is 2.55 Å. There are a spread of Mo(1)-Se(2) bond distances ranging from 2.56-2.67 Å. Ag(1) is bonded in a distorted linear geometry to two equivalent Se(1) and six equivalent Se(2) atoms. Both Ag(1)-Se(1) bond lengths are 2.53 Å. All Ag(1)-Se(2) bond lengths are 3.32 Å. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded in a 4-coordinate geometry to three equivalent Mo(1) and one Ag(1) atom. In the second Se site, Se(2) is bonded in a 5-coordinate geometry to four equivalent Mo(1) and one Ag(1) atom.
