Ti2Cu3 crystallizes in the tetragonal I4/mmm space group. Ti(1) is bonded in a 9-coordinate geometry to four equivalent Cu(2) and five equivalent Cu(1) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 9-coordinate geometry to five equivalent Ti(1) and four equivalent Cu(1) atoms. In the second Cu site, Cu(2) is bonded in a body-centered cubic geometry to eight equivalent Ti(1) atoms.
Ti2Cu3 crystallizes in the tetragonal I4/mmm space group. Ti(1) is bonded in a 9-coordinate geometry to four equivalent Cu(2) and five equivalent Cu(1) atoms. All Ti(1)-Cu(2) bond lengths are 2.65 Å. There are four shorter (2.62 Å) and one longer (2.68 Å) Ti(1)-Cu(1) bond length. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 9-coordinate geometry to five equivalent Ti(1) and four equivalent Cu(1) atoms. All Cu(1)-Cu(1) bond lengths are 2.53 Å. In the second Cu site, Cu(2) is bonded in a body-centered cubic geometry to eight equivalent Ti(1) atoms.
