The crystal structure described by Pd5Sb2 crystallizes in the hexagonal P6_3cm space group. There are six inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 1-coordinate geometry to one Pd(2), one Pd(6), two equivalent Sb(1), and three equivalent Sb(2) atoms. In the second Pd site, Pd(2) is bonded in a 13-coordinate geometry to one Pd(1), two equivalent Pd(3), three equivalent Pd(4), three equivalent Pd(5), one Sb(2), one Sb(3), and two equivalent Sb(1) atoms. In the third Pd site, Pd(3) is bonded in a 4-coordinate geometry to three equivalent Pd(2), one Sb(1), and three equivalent Sb(2) atoms. In the fourth Pd site, Pd(4) is bonded in a 3-coordinate geometry to one Pd(6), three equivalent Pd(2), one Sb(3), and two equivalent Sb(2) atoms. In the fifth Pd site, Pd(5) is bonded in a 4-coordinate geometry to one Pd(6), three equivalent Pd(2), one Sb(2), one Sb(3), and two equivalent Sb(1) atoms. In the sixth Pd site, Pd(6) is bonded in a 13-coordinate geometry to three equivalent Pd(1), three equivalent Pd(4), three equivalent Pd(5), one Sb(3), and three equivalent Sb(2) atoms. There are three inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a 10-coordinate geometry to one Pd(3), three equivalent Pd(1), three equivalent Pd(2), and three equivalent Pd(5) atoms. In the second Sb site, Sb(2) is bonded in a 10-coordinate geometry to one Pd(2), one Pd(5), one Pd(6), two equivalent Pd(3), two equivalent Pd(4), and three equivalent Pd(1) atoms. In the third Sb site, Sb(3) is bonded in a 10-coordinate geometry to one Pd(6), three equivalent Pd(2), three equivalent Pd(4), and three equivalent Pd(5) atoms. is represented by the CIF file [CIF]
