In the title complex, [Co(C(15)H(12)N(3)O(4))(2)Cl(C(6)H(7)N)], the Co(III) ion is coordinated by two N atoms and two O atoms from two deprotonated Schiff base ligands, one N atom from a 4-methyl-pyridine ligand and one Cl atom, forming a distorted octa-hedral geometry. The Co(III) ion is displaced by 0.038 (2) Å from the equatorial plane towards the axial Cl atom.

Cobalt Complexes with Aminophenolate Ligands: Spin Crossover and Ligand Versatility.

A search for switchable molecules has afforded a family of cobalt complexes featuring derivatives of 2-aminophenol: 4,6-di--butyl aminophenol (HL) and 2-anilino-4,6-di--butyl aminophenol (HL). The heteroleptic cobalt complexes incorporate a Metpa ligand (tpa = tris(2-pyridylmethyl)amine; = 0-3), which involves the methylation of the 6-position of the pyridine ring). Eight members of this family have been synthesized and characterized: [Co(HL)(tpa)](BPh) (), [Co(HL)(Metpa)](BPh) (), [Co(L)(Metpa)](BPh) (), [Co(HL)(Metpa)](BPh) (), [Co(L)(Metpa)](BPh) (), [Co(HL)(tpa)] (BPh)(ClO) (), [Co(L)(tpa)](BPh)(ClO) () and [Co(HL)(Metpa)](BPh) (), where the aminophenol-derived ligands are monoanionic in either the open shell radical iminosemiquinonate (L) or the closed shell protonated aminophenolate (HL).

Density functional theory (DFT) calculations indicate that [Co(HO)] reacts with two HO molecules to form [(HO)Co(OOH)(HO)] reactant complexes, which decompose through three distinct pathways depending on the relative orientation between the coordinated OOH and HO ligands. The reactive intermediates produced via these activation pathways include hydroperoxyl (OOH)/superoxide (O) radicals, singlet oxygen (O), and Co(III) species [(HO)Co(O)], [(HO)Co(OH)], and [(HO)Co(OH)]. The Co(III) species display from moderate to strong oxidizing abilities that have long been overlooked.

To fulfil their potential, such materials need to be engineered to respond to specific variations in biological conditions. In this work, we present a series of pH/redox dual-responsive hybrid nanoparticles featuring an amphiphilic shell polymer and a pH-responsive core polymer.

Article Synopsis
- The proposed method combines electrochemical leaching and solvent extraction to effectively recover lithium (Li) and cobalt (Co) from used lithium-ion batteries.
- Electrochemical leaching converts solid LiCoO to soluble Li and Co, achieving up to a 7-fold increase in extraction yields compared to traditional acid leaching methods.
- This process not only improves the efficiency of metal recovery while minimizing chemical use and environmental impact, but also shows strong kinetic performance, suggesting cost benefits and reduced pollution.
