Cl is weak or strong ligand
WebRhenium(I) complexes of type [Re(CO)3(NN)Cl] (NN = α-diimine) with MLCT absorption in the orange-red region of the visible spectrum have been synthesized and fully characterized, including single crystal X-ray diffraction on two complexes. The strong bathochromic shift of MLCT absorption was achieved through extension of the π-system of the electron-poor … WebNov 5, 2024 · Whether F- "behaves" as a strong- or weak-field ligand in these complexes has nothing to do with fluoride itself, because fluoride is a constant factor in all of these examples. It's not some magical property of fluoride that's being turned on or off depending on what complex it's in.

WebOct 12, 2015 · From problems I have been doing and google searches, I have found that H20 is a weak field ligand and NH3 is strong field. I can't understand why [NiF6]2- is diamagnetic. F- should be a weak field ligand, which would mean it would lead to a high spin complex. The Ni should have an oxidation state of +4 making it d6, and in a high … WebOct 27, 2024 · The WOC experiments suggest that the stability of monodentate (chloride) ligand strongly correlates to catalytic performance, which follows the trend 1>2>5≥3>4. This is also substantiated by quantum chemical calculations, which indicate a stronger binding for the chloride ligand based on the extended π-systems in compounds 2 and 3.

WebAnswer (1 of 2): A really important thing you have to understand here is that; The strength of a ligand actually depends upon the metal atom to which it is coordinated to. For eg; Cl- is considered as a weak ligand generally. But if you consider the complex [PtCl4]2- here Cl acts as a strong fie...
WebMay 19, 2024 · Both tetrahedral and square planar isomers coexist in solutions. Weak field ligands, favor tetrahedral geometry and strong field ligands favor the square planar isomer. Both weak field ( C l X −) and strong field ( P P h X 3) ligands comprise N i C l X 2 ( P P h X 3) X 2, hence this compound is borderline between the two geometries.
