The structure described by Pd2Ge crystallizes in the hexagonal P-62m space group. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a 5-coordinate geometry to one Ge(2) and four equivalent Ge(1) atoms. In the second Pd site, Pd(2) is bonded to two equivalent Ge(1) and two equivalent Ge(2) atoms to form a mixture of distorted edge and corner-sharing PdGe4 tetrahedra. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 9-coordinate geometry to three equivalent Pd(2) and six equivalent Pd(1) atoms. In the second Ge site, Ge(2) is bonded in a 9-coordinate geometry to three equivalent Pd(1) and six equivalent Pd(2) atoms. is represented by the CIF card [CIF]
