YPd7B2 crystallizes in the cubic Fm-3m space group. Y(1) is bonded to twelve equivalent Pd(1) atoms to form YPd12 cuboctahedra that share corners with twelve equivalent Y(1)Pd12 cuboctahedra, faces with six equivalent Pd(2)Pd12 cuboctahedra, and faces with eight equivalent B(1)Pd6 octahedra. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a distorted square co-planar geometry to two equivalent Y(1), two equivalent Pd(2), and two equivalent B(1) atoms. In the second Pd site, Pd(2) is bonded to twelve equivalent Pd(1) atoms to form PdPd12 cuboctahedra that share corners with twelve equivalent Pd(2)Pd12 cuboctahedra, faces with six equivalent Y(1)Pd12 cuboctahedra, and faces with eight equivalent B(1)Pd6 octahedra. B(1) is bonded to six equivalent Pd(1) atoms to form BPd6 octahedra that share corners with six equivalent B(1)Pd6 octahedra, faces with four equivalent Y(1)Pd12 cuboctahedra, and faces with four equivalent Pd(2)Pd12 cuboctahedra. The corner-sharing octahedra are not tilted.

All Y(1)-Pd(1) bond lengths are 3.00 Å. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a distorted square co-planar geometry to two equivalent Y(1), two equivalent Pd(2), and two equivalent B(1) atoms. Both Pd(1)-Pd(2) bond lengths are 3.00 Å. Both Pd(1)-B(1) bond lengths are 2.12 Å. In the second Pd site, Pd(2) is bonded to twelve equivalent Pd(1) atoms to form PdPd12 cuboctahedra that share corners with twelve equivalent Pd(2)Pd12 cuboctahedra, faces with six equivalent Y(1)Pd12 cuboctahedra, and faces with eight equivalent B(1)Pd6 octahedra.
