The material described by Ho7Co6Sn23 crystallizes in the trigonal P-3m1 space group. There are two inequivalent Ho sites. In the first Ho site, Ho(1) is bonded in a 18-coordinate geometry to six equivalent Co(1), six equivalent Sn(3), and six equivalent Sn(5) atoms. In the second Ho site, Ho(2) is bonded in a 12-coordinate geometry to two equivalent Co(1), one Sn(1), one Sn(2), two equivalent Sn(3), two equivalent Sn(5), and four equivalent Sn(4) atoms. Co(1) is bonded in a 9-coordinate geometry to one Ho(1), two equivalent Ho(2), one Sn(1), one Sn(4), two equivalent Sn(3), and two equivalent Sn(5) atoms. There are six inequivalent Sn sites. In the first Sn site, Sn(6) is bonded in a 6-coordinate geometry to six equivalent Sn(5) atoms. In the second Sn site, Sn(1) is bonded in a 7-coordinate geometry to three equivalent Ho(2), three equivalent Co(1), and one Sn(2) atom. In the third Sn site, Sn(2) is bonded in a 3-coordinate geometry to three equivalent Ho(2) and one Sn(1) atom. In the fourth Sn site, Sn(3) is bonded in a 2-coordinate geometry to one Ho(1), two equivalent Ho(2), and two equivalent Co(1) atoms. In the fifth Sn site, Sn(4) is bonded in a 5-coordinate geometry to four equivalent Ho(2), one Co(1), and one Sn(5) atom. In the sixth Sn site, Sn(5) is bonded in a 7-coordinate geometry to one Ho(1), two equivalent Ho(2), two equivalent Co(1), one Sn(4), and one Sn(6) atom. is represented by the CIF card [CIF]
