AgGa2Bi crystallizes in the trigonal R3m space group. Ag(1) is bonded in a distorted linear geometry to three equivalent Ga(1), four equivalent Ga(2), and four equivalent Bi(1) atoms. All Ag(1)-Ga(1) bond lengths are 3.15 Å. There is one shorter (2.66 Å) and three longer (3.26 Å) Ag(1)-Ga(2) bond lengths. There is one shorter (2.66 Å) and three longer (3.26 Å) Ag(1)-Bi(1) bond lengths. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 7-coordinate geometry to three equivalent Ag(1), one Ga(2), and three equivalent Bi(1) atoms. The Ga(1)-Ga(2) bond length is 2.66 Å. All Ga(1)-Bi(1) bond lengths are 2.93 Å. In the second Ga site, Ga(2) is bonded in a 8-coordinate geometry to four equivalent Ag(1), one Ga(1), and three equivalent Bi(1) atoms. All Ga(2)-Bi(1) bond lengths are 3.15 Å. Bi(1) is bonded in a 10-coordinate geometry to four equivalent Ag(1), three equivalent Ga(1), and three equivalent Ga(2) atoms.
