European Journal of Inorganic Chemistry, Volume 2022, Issue 26, September 19, 2022., 2022 A comparative study of three related diruthenium complex redox systems reveals notably small effects from asymmetry in 1(PF6) as compared to symmetrical analogues. Electrochemical comproportionation constants, EPR data and near IR absorbance of the intermediates do not reflect the asymmetry in spite of the slanted spin distribution.

Tunable Optical Molecular Thermometers Based on Metallacrowns
Journal of the American Chemical Society, 2022 The effect of ligands' energy levels on thermal dependence of lanthanide emission was examined to create new molecular nanothermometers. A series of Ln2Ga8L8'L8″ metallacrowns (shorthand Ln2L8'), where Ln = Gd3+, Tb3+, or Sm3+ (H3L' = salicylhydroxamic acid (H3shi), 5-methylsalicylhydroxamic acid (H3mshi), 5-methoxysalicylhydroxamic acid (H3moshi), and

European Journal of Inorganic Chemistry, Volume 2022, Issue 22, August 8, 2022., 2022 A methylmercaptobenzo hydroxamic acid (mmbHA) ligand has been synthesized, which is suitable to form 12‐metallacrown (MC)‐4 structures. Two distinct copper(II) based MC systems were synthesized and structurally analyzed. The use of pyridine as co‐ligand led to a drastic change of the mmbHA coordination mode and thus to the formation of a discrete MC in
