The formation of a cocrystallized coordination compound, [Pd-3(D-pen)(3)](2)center dot[M(en)(3)] (ClO4)(3) (D-H(2)pen = D-penicillamine; M = Co-III or Rh-III), from [Pd-3(D-pen)(3)] and [M(en)(3)](ClO4)(3) is reported. In this compound, only the Delta-configurational [M(en)(3)](3+) cations were incorporated when its racemic (Delta/Lambda) isomer was employed. Besides this enantioselective incorporation of complex cations, this compound was found to show the selective incorporation of ClO4- as; the anion species.
