Octadecanuclear Macrocycles and Nonanuclear Bowl-Shaped Structures Based on Two Analogous Pyridyl-Substituted Imidazole-4,5-dicarboxylate Ligands

Two types of unprecedented Cp*Rh-based (Cp* = η5-C5Me5) complexes, two octadeca­nuclear macrocycles, and a nona­nuclear bowl-shaped complex have been synthesized from two analogous pyridyl-functionalized imidazole-4,5-dicarboxylate ligands, 2-(pyridin-4-yl)-1H-imid­azole-4,5-dicarboxylate ligand and 2-(pyridin-3-yl)-1H-imid­azole-4,5-dicarboxylate ligand, respectively.
