The structure described by Er3Pd4 crystallizes in the trigonal R-3 space group. Er(1) is bonded in a 9-coordinate geometry to one Pd(1), one Pd(2), and seven equivalent Pd(3) atoms. There are three inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 6-coordinate geometry to six equivalent Er(1) atoms. In the second Pd site, Pd(2) is bonded in a distorted octahedral geometry to six equivalent Er(1) atoms. In the third Pd site, Pd(3) is bonded in a 10-coordinate geometry to seven equivalent Er(1) and three equivalent Pd(3) atoms. is represented by the CIF file [CIF]
