The material described by Ir2Ga9 crystallizes in the monoclinic P2_1/c space group. Ir(1) is bonded in a 9-coordinate geometry to one Ga(1), two equivalent Ga(2), two equivalent Ga(3), two equivalent Ga(4), and two equivalent Ga(5) atoms. There are five inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a distorted linear geometry to two equivalent Ir(1) atoms. In the second Ga site, Ga(2) is bonded in a 2-coordinate geometry to two equivalent Ir(1) atoms. In the third Ga site, Ga(3) is bonded in a 2-coordinate geometry to two equivalent Ir(1) atoms. In the fourth Ga site, Ga(4) is bonded in a distorted bent 120 degrees geometry to two equivalent Ir(1) atoms. In the fifth Ga site, Ga(5) is bonded in a 2-coordinate geometry to two equivalent Ir(1) atoms. is represented by the CIF card [CIF]
