The compound described by Pd6BiSe crystallizes in the trigonal R-3m space group. There are three inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 1-coordinate geometry to four equivalent Pd(3), three equivalent Bi(1), and one Se(1) atom. In the second Pd site, Pd(2) is bonded in a 3-coordinate geometry to four equivalent Pd(3), one Bi(1), and three equivalent Se(1) atoms. In the third Pd site, Pd(3) is bonded in a 11-coordinate geometry to four equivalent Pd(1), four equivalent Pd(2), and three equivalent Bi(1) atoms. Bi(1) is bonded in a 14-coordinate geometry to two equivalent Pd(2), six equivalent Pd(1), and six equivalent Pd(3) atoms. Se(1) is bonded in a body-centered cubic geometry to two equivalent Pd(1) and six equivalent Pd(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
