Ca3Pd2 crystallizes in the trigonal R-3 space group. There are three inequivalent Ca sites. In the first Ca site, Ca(1) is bonded in an octahedral geometry to six equivalent Pd(1) atoms. In the second Ca site, Ca(2) is bonded in a 6-coordinate geometry to six equivalent Pd(1) atoms. In the third Ca site, Ca(3) is bonded in a 5-coordinate geometry to five equivalent Pd(1) atoms. Pd(1) is bonded in a 9-coordinate geometry to one Ca(1), two equivalent Ca(2), five equivalent Ca(3), and one Pd(1) atom.
Ca3Pd2 crystallizes in the trigonal R-3 space group. There are three inequivalent Ca sites. In the first Ca site, Ca(1) is bonded in an octahedral geometry to six equivalent Pd(1) atoms. All Ca(1)-Pd(1) bond lengths are 3.09 Å. In the second Ca site, Ca(2) is bonded in a 6-coordinate geometry to six equivalent Pd(1) atoms. There are three shorter (2.92 Å) and three longer (3.11 Å) Ca(2)-Pd(1) bond lengths. In the third Ca site, Ca(3) is bonded in a 5-coordinate geometry to five equivalent Pd(1) atoms. There are a spread of Ca(3)-Pd(1) bond distances ranging from 2.99-3.37 Å. Pd(1) is bonded in a 9-coordinate geometry to one Ca(1), two equivalent Ca(2), five equivalent Ca(3), and one Pd(1) atom. The Pd(1)-Pd(1) bond length is 2.86 Å.
