%X The β,β′-bis(triisopropylsiloxy)phenyl-1,4-diisocyanide 3 and [Ir(Cp*)Cl2]2 were used for the stepwise assembly of the [Ir(Cp*)Cl] cornered molecular square [6](Cl)4. Synthesis of the tetrakis(diisocyanide) bridged molecular square [Ir(Cp*)Cl(3)]4(BF4)4 [5](BF4)4 followed by cleavage of the O–Si(i-Pr)3 bonds of the diisocyanide bridges with HCl/i-PrOH led to an intramolecular attack of the liberated hydroxyl groups at the isocyanide carbon atoms with formation of molecular square [6](Cl)4 featuring four dicarbene linkers.
