The material described by BaCu2Ga crystallizes in the trigonal R-3m space group. Ba(1) is bonded in a 8-coordinate geometry to eight equivalent Cu(1) atoms. Cu(1) is bonded in a 10-coordinate geometry to four equivalent Ba(1), three equivalent Cu(1), and three equivalent Ga(1) atoms. Ga(1) is bonded in a distorted hexagonal planar geometry to six equivalent Cu(1) atoms. is represented by the CIF file [CIF]
