The structure described by Pd2As crystallizes in the orthorhombic Cmc2_1 space group. There are four inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 10-coordinate geometry to one Pd(2), two equivalent Pd(4), three equivalent Pd(3), one As(2), and three equivalent As(1) atoms. In the second Pd site, Pd(2) is bonded in a 11-coordinate geometry to one Pd(1), two equivalent Pd(3), four equivalent Pd(4), two equivalent As(1), and two equivalent As(2) atoms. In the third Pd site, Pd(3) is bonded in a 10-coordinate geometry to two equivalent Pd(2), three equivalent Pd(1), two equivalent As(2), and three equivalent As(1) atoms. In the fourth Pd site, Pd(4) is bonded in a 4-coordinate geometry to two equivalent Pd(1), four equivalent Pd(2), and four equivalent As(2) atoms. There are two inequivalent As sites. In the first As site, As(1) is bonded in a 8-coordinate geometry to two equivalent Pd(2), three equivalent Pd(1), and three equivalent Pd(3) atoms. In the second As site, As(2) is bonded in a 9-coordinate geometry to one Pd(1), two equivalent Pd(2), two equivalent Pd(3), and four equivalent Pd(4) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
