The crystal structure described by Ti10CuSn6 crystallizes in the trigonal P-31m space group. There are three inequivalent Ti sites. In the first Ti site, Ti(1) is bonded in a 8-coordinate geometry to two equivalent Ti(2) and six equivalent Sn(1) atoms. In the second Ti site, Ti(2) is bonded in a 8-coordinate geometry to two equivalent Ti(1) and six equivalent Sn(1) atoms. In the third Ti site, Ti(3) is bonded in a 6-coordinate geometry to one Cu(1) and five equivalent Sn(1) atoms. Cu(1) is bonded in an octahedral geometry to six equivalent Ti(3) atoms. Sn(1) is bonded in a 9-coordinate geometry to two equivalent Ti(1), two equivalent Ti(2), and five equivalent Ti(3) atoms. is represented by the CIF card [CIF]
