Ca2Pd3Ge crystallizes in the trigonal R-3m space group. Ca(1) is bonded in a 12-coordinate geometry to nine equivalent Pd(1) and three equivalent Ge(1) atoms. Pd(1) is bonded to six equivalent Ca(1), four equivalent Pd(1), and two equivalent Ge(1) atoms to form distorted PdCa6Ge2Pd4 cuboctahedra that share corners with four equivalent Ge(1)Ca6Pd6 cuboctahedra, corners with fourteen equivalent Pd(1)Ca6Ge2Pd4 cuboctahedra, edges with six equivalent Pd(1)Ca6Ge2Pd4 cuboctahedra, faces with six equivalent Ge(1)Ca6Pd6 cuboctahedra, and faces with twelve equivalent Pd(1)Ca6Ge2Pd4 cuboctahedra. Ge(1) is bonded to six equivalent Ca(1) and six equivalent Pd(1) atoms to form GeCa6Pd6 cuboctahedra that share corners with six equivalent Ge(1)Ca6Pd6 cuboctahedra, corners with twelve equivalent Pd(1)Ca6Ge2Pd4 cuboctahedra, edges with six equivalent Ge(1)Ca6Pd6 cuboctahedra, and faces with eighteen equivalent Pd(1)Ca6Ge2Pd4 cuboctahedra.
Ca2Pd3Ge crystallizes in the trigonal R-3m space group. Ca(1) is bonded in a 12-coordinate geometry to nine equivalent Pd(1) and three equivalent Ge(1) atoms. There are three shorter (3.01 Å) and six longer (3.22 Å) Ca(1)-Pd(1) bond lengths. All Ca(1)-Ge(1) bond lengths are 3.27 Å. Pd(1) is bonded to six equivalent Ca(1), four equivalent Pd(1), and two equivalent Ge(1) atoms to form distorted PdCa6Ge2Pd4 cuboctahedra that share corners with four equivalent Ge(1)Ca6Pd6 cuboctahedra, corners with fourteen equivalent Pd(1)Ca6Ge2Pd4 cuboctahedra, edges with six equivalent Pd(1)Ca6Ge2Pd4 cuboctahedra, faces with six equivalent Ge(1)Ca6Pd6 cuboctahedra, and faces with twelve equivalent Pd(1)Ca6Ge2Pd4 cuboctahedra. All Pd(1)-Pd(1) bond lengths are 2.81 Å. Both Pd(1)-Ge(1) bond lengths are 2.62 Å. Ge(1) is bonded to six equivalent Ca(1) and six equivalent Pd(1) atoms to form GeCa6Pd6 cuboctahedra that share corners with six equivalent Ge(1)Ca6Pd6 cuboctahedra, corners with twelve equivalent Pd(1)Ca6Ge2Pd4 cuboctahedra, edges with six equivalent Ge(1)Ca6Pd6 cuboctahedra, and faces with eighteen equivalent Pd(1)Ca6Ge2Pd4 cuboctahedra.
