The crystal structure described by ErPdSi crystallizes in the orthorhombic Pmmn space group. There are three inequivalent Er sites. In the first Er site, Er(1) is bonded in a 12-coordinate geometry to two equivalent Pd(1), four equivalent Pd(2), two equivalent Si(2), and four equivalent Si(1) atoms. In the second Er site, Er(2) is bonded in a 12-coordinate geometry to two equivalent Pd(2), four equivalent Pd(1), two equivalent Si(1), and four equivalent Si(2) atoms. In the third Er site, Er(3) is bonded in a 12-coordinate geometry to three equivalent Pd(1), three equivalent Pd(2), three equivalent Si(1), and three equivalent Si(2) atoms. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 10-coordinate geometry to one Er(1), two equivalent Er(2), three equivalent Er(3), one Pd(1), one Si(2), and two equivalent Si(1) atoms. In the second Pd site, Pd(2) is bonded in a 10-coordinate geometry to one Er(2), two equivalent Er(1), three equivalent Er(3), one Si(1), and three equivalent Si(2) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 10-coordinate geometry to one Er(2), two equivalent Er(1), three equivalent Er(3), one Pd(2), two equivalent Pd(1), and one Si(1) atom. In the second Si site, Si(2) is bonded in a 10-coordinate geometry to one Er(1), two equivalent Er(2), three equivalent Er(3), one Pd(1), and three equivalent Pd(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
