The structure described by Pd7Zn3Ga4 is beta-prime palladium aluminum-derived structured and crystallizes in the trigonal R3 space group. There are three inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 7-coordinate geometry to four equivalent Zn(1), one Ga(2), and two equivalent Ga(1) atoms. In the second Pd site, Pd(2) is bonded in a 7-coordinate geometry to two equivalent Zn(1), one Ga(2), and four equivalent Ga(1) atoms. In the third Pd site, Pd(3) is bonded in a distorted body-centered cubic geometry to three equivalent Zn(1), two equivalent Ga(2), and three equivalent Ga(1) atoms. Zn(1) is bonded in a 7-coordinate geometry to one Pd(3), two equivalent Pd(2), and four equivalent Pd(1) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 7-coordinate geometry to one Pd(3), two equivalent Pd(1), and four equivalent Pd(2) atoms. In the second Ga site, Ga(2) is bonded in a distorted body-centered cubic geometry to two equivalent Pd(3), three equivalent Pd(1), and three equivalent Pd(2) atoms. is represented by the CIF file [CIF]
