BaPd(SeO3)2 crystallizes in the monoclinic C2/c space group. Ba(1) is bonded in a 8-coordinate geometry to two equivalent O(2), two equivalent O(3), and four equivalent O(1) atoms. Pd(1) is bonded in a square co-planar geometry to two equivalent O(2) and two equivalent O(3) atoms. Se(1) is bonded in a distorted trigonal non-coplanar geometry to one O(1), one O(2), and one O(3) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to two equivalent Ba(1) and one Se(1) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one Ba(1), one Pd(1), and one Se(1) atom. In the third O site, O(3) is bonded in a trigonal planar geometry to one Ba(1), one Pd(1), and one Se(1) atom.
