EuPd2As2 crystallizes in the monoclinic Cm space group. Eu(1) is bonded in a 16-coordinate geometry to four equivalent Pd(1), four equivalent Pd(2), four equivalent As(1), and four equivalent As(2) atoms. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 8-coordinate geometry to four equivalent Eu(1), two equivalent As(1), and two equivalent As(2) atoms. In the second Pd site, Pd(2) is bonded in a 8-coordinate geometry to four equivalent Eu(1), two equivalent As(1), and two equivalent As(2) atoms. There are two inequivalent As sites. In the first As site, As(1) is bonded in a 9-coordinate geometry to four equivalent Eu(1), two equivalent Pd(1), two equivalent Pd(2), and one As(2) atom. In the second As site, As(2) is bonded in a 9-coordinate geometry to four equivalent Eu(1), two equivalent Pd(1), two equivalent Pd(2), and one As(1) atom.
EuPd2As2 crystallizes in the monoclinic Cm space group.
