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.
