The compound described by TmMn6Sn5In crystallizes in the hexagonal P-6m2 space group. Tm(1) is bonded to two equivalent Sn(3), three equivalent Sn(1), and three equivalent Sn(2) atoms to form edge-sharing TmSn8 hexagonal bipyramids. Mn(1) is bonded in a 6-coordinate geometry to one In(1), one Sn(1), one Sn(2), one Sn(4), and two equivalent Sn(3) atoms. In(1) is bonded in a 9-coordinate geometry to six equivalent Mn(1) and three equivalent Sn(4) atoms. There are four inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 9-coordinate geometry to three equivalent Tm(1) and six equivalent Mn(1) atoms. In the second Sn site, Sn(2) is bonded in a 9-coordinate geometry to three equivalent Tm(1) and six equivalent Mn(1) atoms. In the third Sn site, Sn(3) is bonded in a 7-coordinate geometry to one Tm(1) and six equivalent Mn(1) atoms. In the fourth Sn site, Sn(4) is bonded in a 9-coordinate geometry to six equivalent Mn(1) and three equivalent In(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
