Ca5Pd2 crystallizes in the monoclinic C2/c space group. There are three inequivalent Ca sites. In the first Ca site, Ca(1) is bonded in a 2-coordinate geometry to three equivalent Pd(1) atoms. In the second Ca site, Ca(3) is bonded to four equivalent Pd(1) atoms to form distorted edge-sharing CaPd4 tetrahedra. In the third Ca site, Ca(2) is bonded in a 3-coordinate geometry to three equivalent Pd(1) atoms. Pd(1) is bonded in a 8-coordinate geometry to two equivalent Ca(3), three equivalent Ca(1), and three equivalent Ca(2) atoms.
Ca5Pd2 crystallizes in the monoclinic C2/c space group. There are three inequivalent Ca sites. In the first Ca site, Ca(1) is bonded in a 2-coordinate geometry to three equivalent Pd(1) atoms. There are a spread of Ca(1)-Pd(1) bond distances ranging from 2.92-3.55 Å. In the second Ca site, Ca(3) is bonded to four equivalent Pd(1) atoms to form distorted edge-sharing CaPd4 tetrahedra. There are two shorter (3.04 Å) and two longer (3.08 Å) Ca(3)-Pd(1) bond lengths. In the third Ca site, Ca(2) is bonded in a 3-coordinate geometry to three equivalent Pd(1) atoms. There are a spread of Ca(2)-Pd(1) bond distances ranging from 2.97-3.19 Å. Pd(1) is bonded in a 8-coordinate geometry to two equivalent Ca(3), three equivalent Ca(1), and three equivalent Ca(2) atoms.
