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