The issue of whether Pd +2 molecular complexes can be formed in metallic palladium has been considered. It has been shown that in the structure of the face-centered cubic palladium crystal lattice, there are the energy and geometric prerequisites for the formation, from the atoms at the centers of adjacent lattice faces, of Pd +2 molecular complexes with a hole in the 4d shell of one atom. The average content of these complexes and holes per palladium atom has been evaluated. Possible mechanism and kinetics of formation of Pd +2 molecular complexes in metallic palladium have been considered.
