The crystal structure described by GdPd3As2 crystallizes in the monoclinic C2/m space group. There are two inequivalent Gd sites. In the first Gd site, Gd(1) is bonded in a 17-coordinate geometry to one Pd(4), two equivalent Pd(2), two equivalent Pd(5), three equivalent Pd(1), three equivalent Pd(3), two equivalent As(1), two equivalent As(2), and two equivalent As(3) atoms. In the second Gd site, Gd(2) is bonded to two equivalent Pd(2), four equivalent Pd(4), two equivalent As(3), and four equivalent As(2) atoms to form GdAs6Pd6 cuboctahedra that share edges with four equivalent Pd(5)Gd4As4Pd4 cuboctahedra and faces with two equivalent Gd(2)As6Pd6 cuboctahedra. There are five inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 6-coordinate geometry to three equivalent Gd(1), one Pd(4), one As(2), and three equivalent As(3) atoms. In the second Pd site, Pd(2) is bonded in a 12-coordinate geometry to one Gd(2), two equivalent Gd(1), one Pd(3), two equivalent Pd(4), two equivalent Pd(5), two equivalent As(1), and two equivalent As(2) atoms. In the third Pd site, Pd(3) is bonded in a 12-coordinate geometry to three equivalent Gd(1), one Pd(2), two equivalent Pd(3), two equivalent Pd(4), one As(3), and three equivalent As(1) atoms. In the fourth Pd site, Pd(4) is bonded in a 12-coordinate geometry to one Gd(1), two equivalent Gd(2), one Pd(1), two equivalent Pd(2), two equivalent Pd(3), one As(1), one As(2), and two equivalent As(3) atoms. In the fifth Pd site, Pd(5) is bonded to four equivalent Gd(1), four equivalent Pd(2), two equivalent As(1), and two equivalent As(2) atoms to form distorted PdGd4As4Pd4 cuboctahedra that share edges with four equivalent Gd(2)As6Pd6 cuboctahedra and faces with two equivalent Pd(5)Gd4As4Pd4 cuboctahedra. There are three inequivalent As sites. In the first As site, As(1) is bonded in a 9-coordinate geometry to two equivalent Gd(1), one Pd(4), one Pd(5), two equivalent Pd(2), and three equivalent Pd(3) atoms. In the second As site, As(2) is bonded in a 9-coordinate geometry to two equivalent Gd(1), two equivalent Gd(2), one Pd(1), one Pd(4), one Pd(5), and two equivalent Pd(2) atoms. In the third As site, As(3) is bonded in a 9-coordinate geometry to one Gd(2), two equivalent Gd(1), one Pd(3), two equivalent Pd(4), and three equivalent Pd(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
