WebIn order to elucidate plausible mechanisms for the fluxional ligand exchange process, we performed DFT calculations using a truncated model complex in which Ph groups were replaced by Me groups. Despite the differences in electronic and steric properties of the resulting phosphines, we observe no qualitative effect on the proposed ligand ...

WebDefine fluxional. fluxional synonyms, fluxional pronunciation, fluxional translation, English dictionary definition of fluxional. n. 1. a. A flow or flowing. b. Continual change. … WebThe effects of chirality of the diphosphine are most notably seen in the 13 C NMR spectrum of the fluxional [9]aneS 3 ligand, resulting in two separate resonances as opposed to … Molecules with polyhapto ligands are often fluxional, also known as stereochemically non-rigid. Two classes of fluxionality are prevalent for organometallic complexes of polyhapto ligands: Case 1, typically: when the hapticity value is less than the number of sp carbon atoms. In such … See more In coordination chemistry, hapticity is the coordination of a ligand to a metal center via an uninterrupted and contiguous series of atoms. The hapticity of a ligand is described with the Greek letter η ('eta'). For example, η … See more The need for additional nomenclature for organometallic compounds became apparent in the mid-1950s when Dunitz, Orgel, and Rich described the structure of the "sandwich complex" ferrocene by X-ray crystallography where an iron atom is "sandwiched" … See more Hapticity must be distinguished from denticity. Polydentate ligands coordinate via multiple coordination sites within the ligand. In this case … See more The η-notation is encountered in many coordination compounds: • Side-on bonding of molecules containing σ-bonds like See more The hapticity of a ligand can change in the course of a reaction. E.g. in a redox reaction: Here one of the η … See more imperial guard 40k army list
