The crystal structure described by Pd4Al3Si is beta-prime palladium aluminum-derived structured and crystallizes in the trigonal R3 space group. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 7-coordinate geometry to six equivalent Al(1) and one Si(1) atom. In the second Pd site, Pd(2) is bonded in a 7-coordinate geometry to five equivalent Al(1) and two equivalent Si(1) atoms. Al(1) is bonded in a 7-coordinate geometry to two equivalent Pd(1) and five equivalent Pd(2) atoms. Si(1) is bonded in a 7-coordinate geometry to one Pd(1) and six equivalent Pd(2) atoms. is represented by the CIF file [CIF]
