Popis:	The single-step multicomponent self-assembly of molecular squares featuring four bridging benzobiscarbenes and four PdII (allyl) or IrI (COD) vertices is presented. Four equivalents of the linear benzobisimidazolium salt [1](PF6 )2 react with two equivalents of [Pd(allyl)Cl]2 or [IrCl(COD)]2 in the presence of Cs2 CO3 to yield the tetranuclear octacarbene molecular squares [2](PF6 )4 (M=Pd) and [3](PF6 )4 (M=Ir), respectively. Compounds [2](PF6 )4 and [3](PF6 )4 feature exclusively M-carbon bonds making them the first purely organometallic molecular squares.
