Synthesis, Characterization, and Electrochemical Properties of Tri‐ and Tetranuclear CoIII‐Oxo Complexes

open access: yesEuropean Journal of Inorganic Chemistry, Volume 28, Issue 24, August 29, 2025.
A series of three tetranuclear and two trinuclear Co(III) carboxylate complexes are synthesized and thoroughly spectroscopically and electrochemically characterized. The relative stability of the tetranuclear versus trinuclear complexes is investigated by density functional theory calculations, and the infrared and ultraviolet/visible spectra are ...

A comparison of microcrystal electron diffraction and X‐ray powder diffraction for the structural analysis of metal–organic frameworks

open access: yesJournal of Applied Crystallography, Volume 58, Issue 2, Page 398-411, April 2025.
Microcrystal electron diffraction (microED) was used to determine the crystal structure of a recently synthesized metal–organic framework (MOF) from powder crystallites. The structural descriptions of two other MOFs by microED are compared with results previously published using X‐ray powder diffraction supported by density functional theory ...

3-Phenyl-6-(2-pyridyl)-1,2,4,5-tetrazine

open access: yesActa Crystallographica Section E, 2008
The title compound, C13H9N5, is the first asymmetric diaryl-1,2,4,5-tetrazine to be crystallographically characterized. We have been interested in this motif for incorporation into supramolecular assemblies based on coordination chemistry.

Estimating causes of maternal death in data‐sparse contexts

open access: yesStatistics in Medicine, Volume 43, Issue 24, Page 4702-4735, 30 October 2024.
Understanding the underlying causes of maternal death across all regions of the world is essential to inform policies and resource allocation to reduce the mortality burden. However, in many countries there exists very little data on the causes of maternal death, and data that do exist do not capture the entire population at risk.
