The material structure described by Sr4(PdP)5 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded to one Pd(3), one Pd(4), three equivalent Pd(1), two equivalent P(4), two equivalent P(5), and three equivalent P(1) atoms to form a mixture of edge and face-sharing SrP7Pd5 cuboctahedra. In the second Sr site, Sr(2) is bonded in a 14-coordinate geometry to two equivalent Pd(2), two equivalent Pd(3), two equivalent Pd(4), two equivalent Pd(5), one P(4), one P(5), two equivalent P(2), and two equivalent P(3) atoms. There are five inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 9-coordinate geometry to six equivalent Sr(1), one P(5), and two equivalent P(1) atoms. In the second Pd site, Pd(2) is bonded to four equivalent Sr(2), two equivalent P(2), and two equivalent P(3) atoms to form a mixture of distorted edge and face-sharing PdSr4P4 cuboctahedra. In the third Pd site, Pd(3) is bonded in a 9-coordinate geometry to two equivalent Sr(1), four equivalent Sr(2), one P(3), and two equivalent P(4) atoms. In the fourth Pd site, Pd(4) is bonded in a 9-coordinate geometry to two equivalent Sr(1), four equivalent Sr(2), one P(2), and two equivalent P(5) atoms. In the fifth Pd site, Pd(5) is bonded to four equivalent Sr(2), two equivalent P(2), and two equivalent P(3) atoms to form a mixture of distorted edge and face-sharing PdSr4P4 cuboctahedra. There are five inequivalent P sites. In the first P site, P(1) is bonded in a 9-coordinate geometry to six equivalent Sr(1), two equivalent Pd(1), and one P(4) atom.
