1 In the two-step reaction (route III), an endocyclic Cd2+ complex, (Cd(L)I2) (3), obtained in the first step was utilized in the following reaction with Cu(CH3CN)4PF6, giving rise to an endo/exocyclic tetranuclear Cu+ complex, (Cu4(L)2(CH3CN)6)(PF6)4 (4), via Cd2+ 2Cu+ substitution, which is not accessible by conventional procedures. Copper CD2 molecule Homo sapiens
