Title: Direct experimental evaluation of ligand-induced backbonding in nickel metallacyclic complexes

Abstract

The details of ligand-induced backbonding in nickel diphosphine π complexes are explored using nickel L-edge (3d←2p) X-ray absorption spectroscopy as a means of quantifying the degree of backbonding derived from direct Ni 3d donation into the π ligand.

Probing Variable Amine/Amide Ligation in NiIIN2S2 Complexes Using Sulfur K-Edge and Nickel L-Edge X-ray Absorption Spectroscopies: Implications for the Active Site of Nickel Superoxide Dismutase

Journal Article Shearer,J. ; Dehestani, A. ; Abanda, F. - Inorganic Chemistry

Nickel superoxide dismutase (NiSOD) is a recently discovered metalloenzyme that catalyzes the disproportionation of O2* into O2 and H2O2. In its reduced state, the mononuclear NiII ion is ligated by two cis-cysteinate sulfurs, an amine nitrogen (from the protein N-terminus), and an amide nitrogen (from the peptide backbone). Unlike many small molecule and metallopeptide-based NiN2S2 complexes, S-based oxygenation is not observed in NiSOD. Herein we explore the spectroscopic properties of a series of three NiIIN2S2 complexes (bisamine-ligated (bmmp-dmed)NiII, amine/amide-ligated (NiII(BEAAM)), and bisamide-ligated (NiII(emi))2) with varying amine/amide ligation to determine the origin of the dioxygen stability of NiSOD.

Journal Article Baker, Michael L. ; Mara, Michael W. ; Yan, James J. ; ... - Coordination Chemistry Reviews

Continual advancements in the development of synchrotron radiation sources have resulted in X-ray based spectroscopic techniques capable of probing the electronic and structural properties of numerous systems. This review gives an overview of the application of metal K-edge and L-edge X-ray absorption spectroscopy (XAS), as well as Kα resonant inelastic X-ray scattering (RIXS), to the study of electronic structure in transition metal sites with emphasis on experimentally quantifying 3d orbital covalency. The specific sensitivities of K-edge XAS, L-edge XAS, and RIXS are discussed emphasizing the complementary nature of the methods. L-edge XAS and RIXS are sensitive to mixing between 3dmore »« less

Relationship between the bite size of diphosphine ligands and tetrahedral distortions of square-planar nickel(II) complexes: Stabilization of nickel(I) and palladium(I) complexes using diphosphine ligands with large bites

Journal Article Miedaner, A. ; DuBois, D.L. ; Haltiwanger, R.C. - Inorganic Chemistry; (United States)

Nickel and palladium complexes of the type (M(L{sub 2}){sub 2})(BF{sub 4}){sub 2} and (M(L{sub 2})(L{sub 2}{prime}))(BF{sub 4}){sub 2} (where L{sub 2} and L{sub 2}{prime} are diphosphine ligands) have been synthesized. The lowest energy electronic absorption band for the nickel complexes decreases in energy as the bite size of the diphosphine ligand increases. Similarly, the half-wave potentials for the Ni(II/I) and Pd(II/O) couples become more positive as the bite size increases. Structural studies of (Ni(dppm){sub 2})(BF{sub 4}){sub 2} (where dppm is bis(diphenylphosphino)methane) and (Ni-(dppb){sub 2})(PF{sub 6}){sub 2} (where dppb is 1,2-bis(diphenylphosphino)benzene) show that increasing the bite size of the diphosphine ligandsmore »« less

Ligand K-edge x-ray adsorption spectroscopic studies of the electronic structure of inorganic model complexes and metalloprotein active sites

Technical Report Shadle, S.E.

Ligand K-edge X-ray absorption spectroscopy (XAS) has been developed as a technique for the investigation of ligand-metal bonding and has been applied to the study of electronic structure in organic model complexes and metalloprotein active sites. Ligand K-edge XAS has been measured at the chloride K-edge for a series of complexes containing chloride ligands bound to open shell d copper ions. The intensity of the pre-edge feature in these spectra reflects the covalency in the half-occupied d{sub x}2{sub {minus}y}2-derived molecular orbital (HOMO) of the complex. The energy of the pre-edge feature is related to both the charge on the ligandmore »« less
L-edge sum rule analysis on 3d transition metal sites: from d ¹⁰ to d ⁰ and towards application to extremely dilute metallo-enzymes

Journal Article Wang, Hongxin ; Friedrich, Stephan ; Li, Lei ; ... - Physical Chemistry Chemical Physics. PCCP (Print)

According to L-edge sum rules, the number of 3d vacancies at a transition metal site is directly proportional to the integrated intensity of the L-edge X-ray absorption spectrum (XAS) for the corresponding metal complex. In this study, the numbers of 3d holes are characterized quantitatively or semi-quantitatively for a series of manganese (Mn) and nickel (Ni) complexes, including the electron configurations 3d ¹⁰ → 3d ⁰. In addition, extremely dilute (<0.1% wt/wt) Ni enzymes were examined by two different approaches: (1) by using a high resolution superconducting tunnel junction X-ray detector to obtain XAS spectra with a very high signal-to-noisemore »« less
