The structure described by Ti5Ge3 crystallizes in the hexagonal P6_3/mcm space group. There are two inequivalent Ti sites. In the first Ti site, Ti(1) is bonded in a 5-coordinate geometry to five equivalent Ge(1) atoms. In the second Ti site, Ti(2) is bonded in a 8-coordinate geometry to two equivalent Ti(2) and six equivalent Ge(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to four equivalent Ti(2) and five equivalent Ti(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
