The results revealed that the precursors, binuclear complexes [(Cp*M)2{1,4-bis(2-pyridylmethyleneamino)benzene}Cl2][OTf]2 (Cp* = η(5)-pentamethylcyclopentadienyl, M = Ir (2a), Rh (2b)), have different preferential configurations, and tetranuclear complexes [(Cp*M)4{1,4-bis(2-pyridylmethyleneamino)benzene}2(p-CDC)2][OTf]4 (M = Ir (3a), Rh (3b)), which were prepared using monodentate p-carborane dicarboxylate and 2a or 2b, showed highly twisted backbones. Likewise, homologous regular rectangular compounds [(Cp*M)4{1,4-{(2-C5H4N)HC=N}2-2,3,5,6-Me4C6}2(p-CDC)2][OTf]4 (M = Ir (4a), Rh (4b)) and [(Cp*M)4{1,4-{(2-C5H4N)HC=N}2-1,5-naphthalene}2(p-CDC)2][OTf]4 (M = Ir (5a), Rh (5b)) were obtained following a similar synthetic route. X-ray determination confirmed that 4b and 5b have stacking channels as well.
