Access to a new family of thioether-linked PSRT ligands, 4-substituted-3,5-bis{[(2-pyridylmethyl)sulfanyl]methyl}-4H-1,2,4-triazoles (analogues the previously studied amino-linked PMRT ligands), has been established. Four such ligands have prepared, PSPhT, PS(i)BuT, PS(t-Bu)PhT, and PS(Me)PhT, with R = Ph, (i)Bu, (t-Bu)Ph, (Me)Ph, respectively. Three dinuclear colorless pale green iron(II) complexes, [Fe(II)2(PSRT)2](BF4)4·solvent, featuring N4S2 donor sets, were prepared. Single-crystal...
Abstract Seventeen cobalt complexes—eleven dinuclear cobalt(II) complexes and three tetranuclear (two mixed valent) of ditopic ligands, with varying N‐donor aromatic bridging moieties pendant pyridine side arms, as well mononuclear Schiff base macrocyclic ligands—have been screened for photocatalytic hydrogen evolution reaction (HER) activity. All 17 are active catalysts the HER, in both DMF aqueous solution, tandem [Ru(bpy) 3 ] 2+ (bpy=2,2′‐bipyridine) photosensitiser. benchmarked to...
A family of five easily prepared tridentate monoanionic 2,5-dipyridyl-3-(R1)-4-(R2)-pyrrolide anions (dppR1,R2)−, varying in the nature R1 and R2 substituents [R1, = CN, Ph; CO2Et, CO2Et; CO2Me, 4-Py; Me; Me, Me], has been used to generate analogous neutral [CoII(dppR1,R2)2] complexes, two which are structurally characterized at both 100 298 K. Both oxidation spin states these complexes can be switched response appropriate external stimuli. All except [CoII(dppMe,Me)2], exhibit gradual...
A family of three new mononuclear complexes the general form [Fe(L(pz))2(NCE)2] has been prepared (L(pz) = 4-p-tolyl-3-(2-pyrazinyl)-5-(2-pyridyl)-1,2,4-triazole; E S, Se, BH3). All exhibit spin crossover, in two cases with hysteresis, T1/2 being predictably tuned by varying coordinated anion.
Abstract Five metal complexes of the dithiolene ligand maleonitriledithiolate (mnt 2− ) with M=V, Fe, Co, Ni, Cu were studied as redox‐active materials for nonaqueous redox flow batteries (RFBs). All five exhibit at least two processes, making them applicable to symmetric RFBs single‐species electrolytes, that is, both negolyte and posolyte. Charge–discharge cycling in a small‐scale RFB gave modest performances [(tea) 2 V mnt ], Co ] whereas [(tea)Fe Ni (tea=tetraethylammonium) failed hold...

Monitoring the spin states of species in solution is a crucial aspect understanding magnetic properties as well spin-labile sensing, supramolecular, catalytic and biochemical processes. Herein, we describe first quantitative variable-pressure variable-temperature method determining solution, demonstrate that it accurate, identify simultaneous T P sensor system.
