K2PdP2 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 8-coordinate geometry to two equivalent Pd(1) and six equivalent P(1) atoms. In the second K site, K(2) is bonded in a 10-coordinate geometry to four equivalent Pd(1) and six equivalent P(1) atoms. Pd(1) is bonded to two equivalent K(1), four equivalent K(2), two equivalent Pd(1), and four equivalent P(1) atoms to form a mixture of distorted face, corner, and edge-sharing PdK6P4Pd2 cuboctahedra. P(1) is bonded in a 9-coordinate geometry to three equivalent K(1), three equivalent K(2), two equivalent Pd(1), and one P(1) atom.
K2PdP2 crystallizes in the orthorhombic Cmcm space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 8-coordinate geometry to two equivalent Pd(1) and six equivalent P(1) atoms. Both K(1)-Pd(1) bond lengths are 3.33 Å. There are two shorter (3.28 Å) and four longer (3.44 Å) K(1)-P(1) bond lengths. In the second K site, K(2) is bonded in a 10-coordinate geometry to four equivalent Pd(1) and six equivalent P(1) atoms. All K(2)-Pd(1) bond lengths are 3.66 Å. There are two shorter (3.38 Å) and four longer (3.64 Å) K(2)-P(1) bond lengths. Pd(1) is bonded to two equivalent K(1), four equivalent K(2), two equivalent Pd(1), and four equivalent P(1) atoms to form a mixture of distorted face, corner, and edge-sharing PdK6P4Pd2 cuboctahedra. Both Pd(1)-Pd(1) bond lengths are 2.95 Å. All Pd(1)-P(1) bond lengths are 2.41 Å. P(1) is bonded in a 9-coordinate geometry to three equivalent K(1), three equivalent K(2), two equivalent Pd(1), and one P(1) atom. The P(1)-P(1) bond length is 2.16 Å.
