Isolation of a Square Pyramidal Bis(amidophenolate)-Supported As(III)-Cation: Coordination-Induced Electromerism at As.
Article in Angewandte Chemie (International ed. in English), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The synthesis and structural characterization of a slightly distorted square pyramidal arsenium cation is reported. Spectroscopic, crystallographic, and computational evidence indicate that coordination of typical Lewis bases to the As(III)-center induces its oxidation to As(V) with concomitant reduction of the supporting, redox-active bis(amidophenolate) ligand. That reaction is reversible and represents a well-defined example of base-induced electromerism in an As-complex. Single electron reduction of the same As(III) species initially generates a ligand-centered radical, which is persistent enough to be observed by EPR but slowly decays to a heterodimer. Preliminary experiments demonstrate the utility of the As(III)-cation as initiator for transfer hydrogenation reactions.
