ScPd3H4 crystallizes in the cubic Pm-3m space group. Sc(1) is bonded to six equivalent H(1) atoms to form ScH6 octahedra that share corners with six equivalent Sc(1)H6 octahedra and edges with twelve equivalent Pd(1)H6 octahedra. The corner-sharing octahedra are not tilted. Pd(1) is bonded to two equivalent H(2) and four equivalent H(1) atoms to form PdH6 octahedra that share corners with six equivalent Pd(1)H6 octahedra, edges with four equivalent Sc(1)H6 octahedra, and edges with eight equivalent Pd(1)H6 octahedra. The corner-sharing octahedra are not tilted. There are two inequivalent H sites. In the first H site, H(1) is bonded in a distorted linear geometry to two equivalent Sc(1) and four equivalent Pd(1) atoms. In the second H site, H(2) is bonded to six equivalent Pd(1) atoms to form corner-sharing HPd6 octahedra. The corner-sharing octahedra are not tilted.

Sc(1) is bonded to six equivalent H(1) atoms to form ScH6 octahedra that share corners with six equivalent Sc(1)H6 octahedra and edges with twelve equivalent Pd(1)H6 octahedra. The corner-sharing octahedra are not tilted. All Sc(1)-H(1) bond lengths are 2.11 Å. Pd(1) is bonded to two equivalent H(2) and four equivalent H(1) atoms to form PdH6 octahedra that share corners with six equivalent Pd(1)H6 octahedra, edges with four equivalent Sc(1)H6 octahedra, and edges with eight equivalent Pd(1)H6 octahedra. The corner-sharing octahedra are not tilted. Both Pd(1)-H(2) bond lengths are 2.11 Å. All Pd(1)-H(1) bond lengths are 2.11 Å. There are two inequivalent H sites.
