Ca5Cu2Cd crystallizes in the monoclinic C2/m space group. There are four inequivalent Ca sites. In the first Ca site, Ca(1) is bonded to one Cu(2), two equivalent Cu(1), and two equivalent Cd(1) atoms to form a mixture of distorted edge, corner, and face-sharing CaCd2Cu3 trigonal bipyramids. In the second Ca site, Ca(2) is bonded to one Cu(2), two equivalent Cu(1), and two equivalent Cd(1) atoms to form a mixture of distorted edge, corner, and face-sharing CaCd2Cu3 trigonal bipyramids. In the third Ca site, Ca(3) is bonded to one Cu(1), two equivalent Cu(2), and two equivalent Cd(1) atoms to form a mixture of distorted edge, corner, and face-sharing CaCd2Cu3 trigonal bipyramids. In the fourth Ca site, Ca(4) is bonded in a 4-coordinate geometry to two equivalent Cu(1), two equivalent Cu(2), and two equivalent Cd(1) atoms. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 9-coordinate geometry to two equivalent Ca(1), two equivalent Ca(2), two equivalent Ca(3), two equivalent Ca(4), and one Cu(1) atom. In the second Cu site, Cu(2) is bonded in a 9-coordinate geometry to one Ca(1), one Ca(2), two equivalent Ca(4), four equivalent Ca(3), and one Cu(2) atom. Cd(1) is bonded in a 10-coordinate geometry to two equivalent Ca(1), two equivalent Ca(2), two equivalent Ca(4), and four equivalent Ca(3) atoms.
