The structure described by Ti8Co3NiSn4 is Heusler-derived structured and crystallizes in the trigonal R-3m space group. There are five inequivalent Ti sites. In the first Ti site, Ti(1) is bonded in a body-centered cubic geometry to one Co(2), three equivalent Co(1), one Sn(2), and three equivalent Sn(1) atoms. In the second Ti site, Ti(2) is bonded in a body-centered cubic geometry to one Co(1), three equivalent Co(2), and four equivalent Sn(1) atoms. In the third Ti site, Ti(3) is bonded in a body-centered cubic geometry to three equivalent Co(1), one Ni(1), one Sn(1), and three equivalent Sn(2) atoms. In the fourth Ti site, Ti(4) is bonded in a body-centered cubic geometry to one Co(1), three equivalent Ni(1), and four equivalent Sn(2) atoms. In the fifth Ti site, Ti(4) is bonded in a body-centered cubic geometry to one Co(1), three equivalent Ni(1), and four equivalent Sn(2) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a body-centered cubic geometry to one Ti(2), one Ti(4), three equivalent Ti(1), and three equivalent Ti(3) atoms. In the second Co site, Co(2) is bonded in a body-centered cubic geometry to two equivalent Ti(1) and six equivalent Ti(2) atoms. Ni(1) is bonded in a body-centered cubic geometry to two equivalent Ti(3) and six equivalent Ti(4) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a body-centered cubic geometry to one Ti(3), three equivalent Ti(1), and four equivalent Ti(2) atoms. In the second Sn site, Sn(2) is bonded in a body-centered cubic geometry to one Ti(1); three equivalent Ti(3); and four Ti(4,4) atoms. is represented by the CIF file [CIF]
