Ca3Cd2 crystallizes in the tetragonal P4_2/mnm space group. There are three inequivalent Ca sites. In the first Ca site, Ca(1) is bonded in a 6-coordinate geometry to six equivalent Cd(1) atoms. In the second Ca site, Ca(3) is bonded in a distorted square co-planar geometry to four equivalent Cd(1) atoms. In the third Ca site, Ca(2) is bonded in a 6-coordinate geometry to six equivalent Cd(1) atoms. Cd(1) is bonded in a 10-coordinate geometry to two equivalent Ca(3), three equivalent Ca(1), three equivalent Ca(2), and two equivalent Cd(1) atoms.
Ca3Cd2 crystallizes in the tetragonal P4_2/mnm space group. There are three inequivalent Ca sites. In the first Ca site, Ca(1) is bonded in a 6-coordinate geometry to six equivalent Cd(1) atoms. There are two shorter (3.26 Å) and four longer (3.43 Å) Ca(1)-Cd(1) bond lengths. In the second Ca site, Ca(3) is bonded in a distorted square co-planar geometry to four equivalent Cd(1) atoms. All Ca(3)-Cd(1) bond lengths are 3.51 Å. In the third Ca site, Ca(2) is bonded in a 6-coordinate geometry to six equivalent Cd(1) atoms. All Ca(2)-Cd(1) bond lengths are 3.31 Å. Cd(1) is bonded in a 10-coordinate geometry to two equivalent Ca(3), three equivalent Ca(1), three equivalent Ca(2), and two equivalent Cd(1) atoms. There is one shorter (3.08 Å) and one longer (3.12 Å) Cd(1)-Cd(1) bond length.
