Long overdue were syntheses of nickel(III) complexes containing aliphatic thiolate ligands. The complex anion [Ni(phmi)] (phmi is the tetraanion of N,N'-1,2-phenylenebis(2-methyl-2-sulfanylpropionamide) has now been isolated-as PPh salt-and structurally characterized. The stability of the nickel(III) complex is attributed to the special properties of the ligand, which abolish or at least retard possible decomposition pathways.

Superoxide dismutase (SOD) enzymes are pivotal in regulating oxidative stress. In order to model Ni containing SOD enzymes, the results of the thermodynamic, spectroscopic and SOD activity studies on the complexes formed between nickel(II) and a NiSOD related peptide, CysCysAspLeuProCysGlyValTyr-NH (), are reported. Cysteine was introduced to replace the first histidine residue in the amino acid sequence of the active site of the NiSOD enzyme.

Nickel excels at facilitating selective radical chemistry, playing a pivotal role in metalloenzyme catalysis and modern cross-coupling reactions. Radicals, being nonpolar and neutral, exhibit orthogonal reactivity to nucleophilic and basic functional groups commonly present in biomolecules. Harnessing this compatibility, we delve into the application of nickel-catalyzed radical pathways in the synthesis of noncanonical peptides and carbohydrates, critical for chemical biology studies and drug discovery.

A liquescent bis(malononitriledithiolato)nickel(III) complex with a bis(methoxyethyl)imidazolium cation, 1[Ni(mnt) ], exhibits three-stage thermochromic modulation of transparency/absorption in the short-wave-infrared (SWIR) region (1000-2500 nm), driven by associated structural changes. Upon heating, the electronic spectra of 1[Ni(mnt) ] in the SWIR region shift to shorter wavelengths accompanying with the solid-liquid phase transition at 76 °C. Further heating to over 109 °C induces a second transition of the electronic spectra, characterized by a blue-shift of the SWIR absorption in the liquid phase.

Treatment of nickel(II) nitrate with the iridium(III) metalloligand -[Ir(apt)] (apt = 3-aminopropanethiolate) gave the trinuclear complex [Ni{Ir(apt)}](NO) ([](NO)), in which the nickel center has a formal oxidation state of +III. Chemical or electrochemical oxidation and reduction of [](NO) generated the corresponding trinuclear complexes [Ni{Ir(apt)}](NO) ([](NO)) and [Ni{Ir(apt)}](NO) ([](NO)) with one-electron oxidated and reduced states, respectively. Single-crystal X-ray crystallography revealed that the nickel center in [](NO) is situated in a highly distorted octahedron due to Jahn-Teller effect, while the nickel center in each of [](NO) and [](NO) adopts a normal octahedral geometry.

There have been many examples of the accelerating effects of acids in electron transfer (ET), oxygen atom transfer (OAT), and hydrogen atom transfer (HAT) reactions. Herein, we report a contrasting effect of acids in the ET, OAT, and HAT reactions of a nickel(III) complex, [Ni(PaPy*)] () in acetone/CHCN (v/v 19:1). was synthesized by reacting [Ni(PaPy*)] () with magic blue or iodosylbenzene in the absence or presence of triflic acid (HOTf), respectively.
