Crystal structure of (acetylacetonato) (dicarbonyl)iridium(I)

13C NMR spectrum of crystalline [Rh(Acac) (CO)2]: A contribution to the discussion on [Rh(Acac) (CO)2] molecular structure in the solid state

“…This may be illustrated by a Inspection of CIF file for previously published structure of 1 ([43], CSD refcode ACABRH02) showed the same difference between O 3 and O 4 contacts. Parallel results were obtained also for iridium analog of 1, [IrAcac(CO) 2 ] ( [49], CSD refcode ACRHCO02).…”

Controlling catalytic activity and selectivity for partial hydrogenation by tuning the environment around active sites in iridium complexes bonded to supports

“…The crystal structure of Ir(CO) 2 (acac) 48 was used to calculate the phase shifts and backscattering amplitudes representing the Ir–C CO , Ir–O CO , and Ir–O s shells, as it was foreseen that the structure of the supported iridium species would be similar to that of this precursor. The Ir–C CO and multiple scattering paths of the Ir–O CO of the carbonyl were fit together to separate out the carbon and oxygen first shells.…”

Iridium Complexes and Clusters in Dealuminated Zeolite HY: Distribution between Crystalline and Impurity Amorphous Regions

“…4 The background was subtracted by using cubic spline routines. Reference backscattering amplitudes and phase shifts were calculated with the software FEEF7 5 from crystallographic data characterizing Ir(CO) 2 (acac) 6 , Ir-Al alloy, Ir-Si alloy, and IrO 2 . 7 The fit models include the following contributions: Ir-C CO , Ir-O CO (taking into account the multiple scattering that is characteristic of a linear Ir-C-O moiety), [8][9] Ir-O zeolite , Ir-Al zeolite , and Ir-Si zeolite .…”
