TiRe is Tetraauricupride structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Ti is bonded in a body-centered cubic geometry to eight equivalent Re atoms. All Ti–Re bond lengths are 2.70 Å. Re is bonded in a body-centered cubic geometry to eight equivalent Ti atoms.
Re24Ti5 is alpha-derived structured and crystallizes in the cubic I-43m space group. The structure is three-dimensional. there are two inequivalent Ti sites. In the first Ti site, Ti is bonded in a 12-coordinate geometry to four equivalent Ti and twelve equivalent Re atoms. All Ti–Ti bond lengths are 3.07 Å. All Ti–Re bond lengths are 3.01 Å. In the second Ti site, Ti is bonded in a 3-coordinate geometry to one Ti and fifteen Re atoms. There are a spread of Ti–Re bond distances ranging from 2.73–3.22 Å. There are two inequivalent Re sites. In the first Re site, Re is bonded in a 1-coordinate geometry to two equivalent Ti and eleven Re atoms. There are a spread of Re–Re bond distances ranging from 2.57–2.90 Å. In the second Re site, Re is bonded to four Ti and eight Re atoms to form a mixture of distorted face, edge, and corner-sharing ReTi4Re8 cuboctahedra. There are one shorter (2.48 Å) and two longer (2.64 Å) Re–Re bond lengths.
Ti2Re crystallizes in the trigonal P-3m1 space group. The structure is two-dimensional and consists of one Ti2Re sheet oriented in the (0, 0, 1) direction. Ti is bonded in a distorted trigonal non-coplanar geometry to three equivalent Re atoms. All Ti–Re bond lengths are 2.67 Å. Re is bonded in a 6-coordinate geometry to six equivalent Ti atoms.
