A molecular rectangle has been obtained from two equivalents of a dicarbene‐bridged dinuclear platinum complex and two equivalents of β,β′‐bis(triisopropylsiloxy)phenyl‐1,4‐diisocyanide. Hydrolysis of the OSi( i Pr) 3 bonds in this complex leads to the formation of two bridging di(NH,O)‐NHC ligands and yields the molecular square (see picture) that features two types of bridging rigid ditopic di‐NHC ligands.
