Description
Summary:A Cp*Rh-based nonanuclear triangular macrocycle complex [(Cp*Rh) 9 L 3 (NO 3 ) 4.5 (MeOH)](OTf) 4.5 ( 1 ), a Cp*Ir-based trinuclear complex [(Cp*Ir) 3 L(MeCN) 4 ](OTf) 3 ( 2 ) and a linear heptanuclear heterometallic complex [(Cp*Ir) 6 ZnL 2 (MeCN) 8 (MeOH) 2 ](OTf) 8 ( 3 ) (Cp* = η 5 -pentamethylcyclopentadienyl) have been synthesized from a 2-(4-(pyridin-4-yl)phenyl)-1 H -imidazole-4,5-dicarboxylic acid proligand. These complexes were further characterized by X-ray crystallography, 1 H NMR, DOSY NMR, IR spectroscopy, and elemental analyses. A novel Cp*Rh-based nonanuclear triangular macrocycle complex has been constructed from 2-(4-(pyridin-4-yl)phenyl)-1 H -imidazole-4,5-dicarboxylate ligands.
