Nickel K- and L 2,3 -edge X-ray absorption spectra (XAS) are discussed for coordinated nickel centers spanning formal oxidation states from II to IV. The ensuing analysis indicates that a physical “+4” state is untenable Ni.
Described herein is the synthesis of NiII complex (tBuMe2tacn)NiII(cycloneophyl) (tBuMe2tacn = 1-tert-butyl-4,7-dimethyl-1,4,7-triazacyclononane, cycloneophyl -CH2CMe2-o-C6H4-) and its reactivity with dioxygen peroxides. The new tBuMe2tacn ligand designed to enhance oxidatively induced bond-forming high-valent Ni intermediates. Tunable chemoselectivity for Csp2-O vs Csp2-Csp3 bond formation was achieved by selecting appropriate solvent reaction conditions. Importantly, use cumene...
Herein, the pyridinophane tetradentate ligand PyNMe 3 is used to isolate and structurally characterize well-defined organometallic Ni( ii ) iii complexes bearing cycloneophyl fragment, an alkyl/aryl C-donor ligand.

Although the connection between symmetry and entropy is not clear, researchers calculate configurational with an ideal gas mixing model all along regardless of which structure they are considering. However, it obvious that crystalline structures have symmetry, while does not. Therefore, same value should be assigned to other structures, such as face-centered-cubic (fcc) hexagonal-close-packed (hcp) structures. Here, we offer a precise definition for determining crystals. We difference in fcc...
Abstract Herein, we report four new chiral 1,4,7‐triazacyclononane (TACN) derivatives and their corresponding nickel(II) chloride complexes. All TACN ligands are bearing one N‐substituent two alkyl (methyl or tert ‐butyl) N‐substituents, have developed a synthetic method for the dimethyl‐substituted derivative, in order to prevent rotational isomers that hinder cyclization reaction. The nickel complexes change coordination geometry significantly depending on steric bulk of N‐alkyl...
