SrPd2Bi2 crystallizes in the monoclinic P2_1/m space group. Sr(1) is bonded in a 17-coordinate geometry to four equivalent Pd(1), four equivalent Pd(2), four equivalent Bi(2), and five equivalent Bi(1) atoms. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 9-coordinate geometry to four equivalent Sr(1), one Bi(1), and four equivalent Bi(2) atoms. In the second Pd site, Pd(2) is bonded in a 10-coordinate geometry to four equivalent Sr(1), two equivalent Pd(2), and four equivalent Bi(1) atoms. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 5-coordinate geometry to five equivalent Sr(1), one Pd(1), and four equivalent Pd(2) atoms. In the second Bi site, Bi(2) is bonded in a 8-coordinate geometry to four equivalent Sr(1) and four equivalent Pd(1) atoms.
