The compound described by TmAgSi crystallizes in the hexagonal P-62m space group. Tm(1) is bonded in a 11-coordinate geometry to six equivalent Ag(1), one Si(2), and four equivalent Si(1) atoms. Ag(1) is bonded in a 12-coordinate geometry to six equivalent Tm(1), two equivalent Ag(1), two equivalent Si(1), and two equivalent Si(2) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 9-coordinate geometry to six equivalent Tm(1) and three equivalent Ag(1) atoms. In the second Si site, Si(2) is bonded in a 9-coordinate geometry to three equivalent Tm(1) and six equivalent Ag(1) atoms. is represented by the CIF file [CIF]
