YbPd7Ga4 crystallizes in the cubic Pm-3m space group. Yb(1) is bonded in a 20-coordinate geometry to eight equivalent Pd(1), eight equivalent Pd(3), and four equivalent Ga(1) atoms. There are three inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 10-coordinate geometry to two equivalent Yb(1), two equivalent Pd(1), two equivalent Pd(3), and four equivalent Ga(1) atoms. In the second Pd site, Pd(2) is bonded to twelve equivalent Ga(1) atoms to form PdGa12 cuboctahedra that share faces with eight equivalent Pd(3)Yb3Ga3Pd6 cuboctahedra and faces with twelve equivalent Ga(1)YbGa4Pd7 cuboctahedra. In the third Pd site, Pd(3) is bonded to three equivalent Yb(1), three equivalent Pd(1), three equivalent Pd(3), and three equivalent Ga(1) atoms to form distorted PdYb3Ga3Pd6 cuboctahedra that share corners with nine equivalent Pd(3)Yb3Ga3Pd6 cuboctahedra, corners with twelve equivalent Ga(1)YbGa4Pd7 cuboctahedra, edges with three equivalent Pd(3)Yb3Ga3Pd6 cuboctahedra,  a faceface with one Pd(2)Ga12 cuboctahedra, faces with six equivalent Pd(3)Yb3Ga3Pd6 cuboctahedra, and faces with nine equivalent Ga(1)YbGa4Pd7 cuboctahedra. Ga(1) is bonded to one Yb(1), one Pd(2), two equivalent Pd(3), four equivalent Pd(1), and four equivalent Ga(1) atoms to form distorted GaYbGa4Pd7 cuboctahedra that share corners with six equivalent Ga(1)YbGa4Pd7 cuboctahedra, corners with eight equivalent Pd(3)Yb3Ga3Pd6 cuboctahedra, edges with four equivalent Ga(1)YbGa4Pd7 cuboctahedra,  a faceface with one Pd(2)Ga12 cuboctahedra, faces with six equivalent Pd(3)Yb3Ga3Pd6 cuboctahedra, and faces with eight equivalent Ga(1)YbGa4Pd7 cuboctahedra.
