BaPd2As2 crystallizes in the tetragonal I4/mmm space group. The structure is three-dimensional. Ba2+ is bonded in a 8-coordinate geometry to eight As3- atoms. There are four shorter (3.43 Å) and four longer (3.50 Å) Ba–As bond lengths. There are two inequivalent Pd2+ sites. In the first Pd2+ site, Pd2+ is bonded in a distorted rectangular see-saw-like geometry to four equivalent As3- atoms. All Pd–As bond lengths are 2.67 Å. In the second Pd2+ site, Pd2+ is bonded in a 5-coordinate geometry to five As3- atoms. There are four shorter (2.57 Å) and one longer (2.65 Å) Pd–As bond lengths. There are two inequivalent As3- sites. In the first As3- site, As3- is bonded in a 8-coordinate geometry to four equivalent Ba2+ and four equivalent Pd2+ atoms. In the second As3- site, As3- is bonded in a 10-coordinate geometry to four equivalent Ba2+, five Pd2+, and one As3- atom. The As–As bond length is 2.81 Å.
