Experimental Evidence for the Noninnocence of o-Aminothiophenolates: Coordination Chemistry of o-Iminothionebenzosemiquinonate(1-) π-Radicals with Ni(II), Pd(II), Pt(II)
TL;DR: Analysis of the geometric features of 120 published structures of complexes containing ligands of the o-aminothiophenolate type show that high precision X-ray crystallography allows to discern the differing protonation and oxidation levels of these ligands.

Common and less-common coordination modes of the typical chelating and heteroaromatic ligands
TL;DR: In this article, different modes of bonding the metals to the most widely spread chelating [β-diketones, o-oxyazomethines, o -oxy(mercapto) derivatives of azoles and azines] and heteroaromatic ligands are generalized and systematized.

Competitive coordination : ambident ligands in the modern chemistry of metal complexes
Alexander D. Garnovskii,Dimitri A. Garnovskii,Igor S. Vasilchenko,Anatolii S. Burlov,Alexander P. Sadimenko,Igor D. Sadekov +5 more
TL;DR: In this paper, the competitive binding of metals in complexes of bi-and poly-dentate ligand systems was surveyed and treated systematically, focusing on nontraditional ways in which typical ligand system are coordinated and on regioselective synthesis as a method for the specific synthesis of metal complexes with a specified location of the coordinate bond.
Book ChapterDOI
Five-and Six-Membered Heteroaromatic Compounds as σ and π Ligands
TL;DR: In this paper, the role of five-and six-membered heteroaromatic compounds as σ and π ligands is discussed and an overview of the structural types that can arise when heterocycles are used as ligands in organometallic derivatives.

Journal ArticleDOI
The alternative nitrogenase of Azotobacter chroococcum is a vanadium enzyme
Robert L. Robson,Robert R. Eady,Toby Richardson,Richard W. Miller,Marie Hawkins,John Postgate +5 more
TL;DR: It is demonstrated here that nitrogen fixation by this strain depends on vanadium and it is shown that its purified nitrogenase is a binary system in which the conventional molybdoprotein is replaced by a vanadoprotein.
Journal ArticleDOI
Isolation of a new vanadium-containing nitrogenase from Azotobacter vinelandii.
TL;DR: A new nitrogenase from Azotobacter vinelandii has been isolated and shown to differ completely from conventional component 1, i.e., the MoFe protein, which can reduce dinitrogen, protons, and acetylene but is only able to utilize 10-15% of its electrons for the reduction of acetylene.
Journal ArticleDOI
X-ray absorption of Azotobacter vinelandii vanadium nitrogenase
TL;DR: In this paper, an X-ray absorption spectroscopic study of A. vinelandii vanadium nitrogenase, Avl', was performed and the local vanadium structure is proposed to resemble a recently synthesized cubane-like VFe/sub 3/S/sub 4/ cluster, and analogies are drawn with the EXAFS-derived structure reported for the molybdenum nitrogenases.

Vanadium K-edge X-ray-absorption spectroscopy of the functioning and thionine-oxidized forms of the VFe-protein of the vanadium nitrogenase from Azotobacter chroococcum.

TL;DR: Vanadium K-edge X-ray-absorption spectra were collected for samples of thionine-oxidized, super-red reduced (during enzyme turnover) and dithionite-reduced VFe-protein of the vanadium nitrogenase of Azotobacter chroococcum (Acl*).
