Ti Ti Ti Ti Ga P
Ti4GaP crystallizes in the trigonal R3m space group. There are two inequivalent Ti sites. In the first Ti site, Ti(1) is bonded in a 2-coordinate geometry to one Ti(2), two equivalent Ti(1), one Ga(1), and two equivalent P(1) atoms. The Ti(1)-Ti(2) bond length is 1.56 Å. Both Ti(1)-Ti(1) bond lengths are 0.90 Å. The Ti(1)-Ga(1) bond length is 1.78 Å. Both Ti(1)-P(1) bond lengths are 2.79 Å. In the second Ti site, Ti(2) is bonded in a 7-coordinate geometry to three equivalent Ti(1), three equivalent Ga(1), and one P(1) atom. All Ti(2)-Ga(1) bond lengths are 3.19 Å. The Ti(2)-P(1) bond length is 3.03 Å. Ga(1) is bonded in a 6-coordinate geometry to three equivalent Ti(1) and three equivalent Ti(2) atoms. P(1) is bonded in a 7-coordinate geometry to one Ti(2) and six equivalent Ti(1) atoms.
