The Lewis Acidity of Bare and Crown Ether‐Complexed Germanium(II) and Tin(II) Cations
Chemistry – A European Journal, Volume 31, Issue 20, April 4, 2025.The Lewis acidity of a variety of dicationic germanium(II) and tin(II) crown ether complexes was assessed by the Gutmann‐Beckett and Fluoride Ion Affinity methods. The germanium(II) centre was found, in general, to be more Lewis acidic than the tin(II) centre. The most promising complexes for catalysis are [Ge([18]crown‐6)][OTf]2 and [Ge([12]crown‐4)2][

Canadian Respiratory Journal, Volume 2, Issue 3, Page 161-171, 1995., 1995 The first section of this concluding part reviews epidemiological studies relating to oxidant exposures. There are convincing data from the eastern section of the continent that ozone, in combination with aerosol sulphates and acid aerosols, is strongly associated with hospital emergency visits and in‐patient admissions for acute respiratory disease ...

Neutrophils as indicators of obesity‐associated inflammation: A systematic review and meta‐analysis
Obesity Reviews, Volume 26, Issue 3, March 2025.Summary Introduction The aim of this study is to evaluate and compare the suitability of routine blood neutrophil values as indicators of obesity‐associated inflammation. Methods In this systematic review and meta‐analysis, we assess absolute neutrophil counts (ANCs) and neutrophil‐to‐lymphocyte ratio (NLR) values in subjects with and without obesity ...

Bis[hydrotris(4-chloro-3,5-dimethylpyrazolyl)borato]nickel(II)
Acta Crystallographica Section E Structure Reports Online, 2005 The title compound, [Ni(C15H19BCl3N6)2] or Ni(Tp*Cl)2, adds to the list of structurally characterized bis(trispyrazolyl)borate–nickel(II) complexes. The two facially coordinating N-donor Tp*Cl ligands impose pseudo-octahedral coordination on the nickel(II) center.

Acta Crystallographica Section C, Volume 80, Issue 5, Page 153-158, May 2024.The coordination chemistry of the hydrotris[3‐(2‐furyl)pyrazol‐1‐yl]borate (Tp2‐Fu) ligand is explored with cerium(III) and dysprosium(III). The difference in Lewis acidity of the ions reveals varying stability in the bis‐Tp2‐Fu lanthanide complexes.The coordination of hydrotris[3‐(2‐furyl)pyrazol‐1‐yl]borate (Tp2‐Fu, C21H16BN6O3) to lanthanide(III ...
