BiPd2O4 crystallizes in the triclinic P-1 space group. There are four inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(4) atoms. In the second Pd site, Pd(2) is bonded in an octahedral geometry to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. In the third Pd site, Pd(3) is bonded in a linear geometry to two equivalent O(2) atoms. In the fourth Pd site, Pd(4) is bonded in a linear geometry to two equivalent O(1) atoms. Bi(1) is bonded in a distorted water-like geometry to one O(1), one O(2), and one O(3) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to one Pd(1), one Pd(4), and one Bi(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one Pd(2), one Pd(3), and one Bi(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Pd(2), one Bi(1), and one O(4) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Pd(1), one Pd(2), and one O(3) atom.
