Altering the nature of coupling by changing the oxidation state in a {Mn6} cage
Watson, Graeme; Schmitt, Wolfgang; Venkatesan, Munuswamy (2020)Polynuclear transition metal complexes have continuously attracted interest owing to their peculiar electronic and magnetic properties which are influenced by the symmetry and connectivity of the metal centres. Understanding ... -
Bioinspired Water Oxidation Using a Mn-Oxo Cluster Stabilized by Non-Innocent Organic Tyrosine Y161 and Plastoquinone Mimics
Schmitt, Wolfgang; Venkatesan, Munuswamy (2020)The complexity and energy demand of the H2O oxidation half-reaction represents the bottleneck for the development of sustainable, environmentally friendly H2 economies using H2O as energy feedstock. In Nature, photosynthetic ... -
A cubane-type manganese complex with H2O oxidation capabilities
Watson, Graeme; Schmitt, Wolfgang; Venkatesan, Munuswamy (2020)We report the synthesis and characterisation of [Mn8K2O4(OH)2((CH3)3CCOO)16(CH3CN)2] whose cluster core shares some features with the oxygen evolving complex (OEC), the natural water oxidation catalyst. Importantly, this ... -
Modulating Structural and Electronic Properties of Rare Archimedean and Johnson-Type Mn Cages
Schmitt, Wolfgang; Venkatesan, Munuswamy; Watson, Graeme (2021)High-nuclearity Mn complexes have attracted significant scientific attention due to their fascinating magnetic properties and their relevance to bioinorganic systems and catalysis. In this work, we demonstrate how the ... -
Structural variation in cation-assisted assembly of high-nuclearity Mn arsonate and phosphonate wheels
Schmitt, Wolfgang; Venkatesan, Munuswamy (2016)Comproportionation reactions between MnCl2 and KMnO4 in the presence of arsonate or phosphonate ligands promote the cation-assisted assembly of high-nuclearity, wheel-shaped or toroidal {Mn8} (1) and {Mn24} (2) complexes; ...
