[H_3–nFe₄(CO)₁₂(IrCOD)]ⁿ⁻(n= 1, 2) and [H₂Fe₃(CO)₁₀(IrCOD)]⁻Bimetallic Fe–Ir Hydride Carbonyl Clusters

Organometallics (2014)

Marco Bortoluzzi Iacopo Ciabatti Cristina Femoni Mohammad Hayatifar Maria Carmela Iapalucci

The reaction of [HFe4(CO)12]3– (1) with [Ir(COD)Cl]2 results in the formation of the bimetallic Fe–Ir monohydride carbonyl cluster [HFe4(CO)12(IrCOD)]2– (2). This is quantitatively protonated by strong acids to the dihydride [H2Fe4(CO)12(IrCOD)]− (3). Further addition of acids to 3 results in the tetranuclear dihydride [H2Fe3(CO)10(IrCOD)]− (4) via formal oxidative elimination of a Fe(CO)2 fragment. Compounds 2–4 have been fully characterized by means of 1H VT NMR spectroscopy, X-ray crystallography, and DFT calculations. In 2 and 3 the Fe4Ir cluster core adopts a trigonal bipyramidal geometry, while the Fe3Ir core in 4 is tetrahedral. In addition, 1H VT NMR studies indicate that 2 and 3 are fluxional in solution, whereas 4 is not.

Dirhodium(II) carboxylates as building blocks. Macrocyclic dimers with vertically stacked Rh24+ units

Dalton (2000)

Richard P. Bonar‐Law J.F. Bickley Cristina Femoni Alexander Steiner

Reaction of Rh2(OAc)4 and H2L (=2,7-di-tert-butyl-9,9-dimethyl-4,5-xanthenedicarboxylic acid) in N,N-dimethylaniline gave the singly bridged dimer (AcO)3Rh2LRh2(OAc)3 and three doubly bridged dimers, (AcO)2Rh2L2Rh2(OAc)2, (HL)(AcO)Rh2L2Rh2(OAc)2, and (HL)(AcO)Rh2L2Rh2(OAc)(HL). Crystal structures of the last two compounds showed a macrocyclic core with a trans arrangement of bridging dicarboxylates, with one or two of the four remaining acetate ligands replaced by a bridging ligand bound through one carboxylate only. The rhodium cages are separated by 4.5 Å in the direction of the Rh–Rh axes, and offset horizontally by 2.5 Å so that a rhodium atom of one cage lies over a carboxylate oxygen of the other, with Rh⋯O distances of 2.248–2.286 Å.

Solid-state assemblies and optical properties of conjugated oligomers combining fluorene and thiophene units

Science & Engineering Faculty (2006)

Mathieu Surin Prashant Sonar Andrew C. Grimsdale Kläus Müllen Steven De Feyter

Two conjugated oligomers, representing elementary segments of fluorene-thiophene copolymers, are compared in terms of the microscopic morphology and the optical properties of thin deposits. The atomic force microscopy morphological data and the solid-state absorption and emission spectra are interpreted in terms of the assembly of the conjugated molecules. The compound with a terthiophene central unit and fluorene end-groups shows well-defined monolayer-by-monolayer assembly into micrometer-long stripe-like structures, with a crystalline herringbone-type organization within the monolayers. Polarized confocal microscopy indicates a strong orientation of the crystalline domains within the stripes. In contrast, the compound with a terfluorene central unit and thiophene end groups forms no textured aggregates and the optical spectra in the solid-state are very similar to those recorded in solution, suggesting that the molecules interact only weakly in the solid. The difference in behaviour between the two compounds most probably originates from their different capability to form densely-packed assemblies of interacting π-systems.
