# Description of a Non-Canonical AsPt Blue Species Originating from the Aerobic Oxidation of AP-1 in Aqueous Solution

## TL;DR

Scientists discovered a unique blue chemical species formed when a specific compound is oxidized in water.

## Contribution

The paper identifies and characterizes a new non-canonical blue species resulting from the oxidation of arsenoplatin-1.

## Key findings

- A blue species named 'AsPt blue' forms during the aerobic oxidation of AP-1 in aqueous solution.
- The formation of AsPt blue involves complex processes revealed through a multi-technique approach.

## Abstract

The peculiar behavior of arsenoplatin-1, ([Pt(µ-NHC(CH3)O)2ClAs(OH)2], AP-1), in aqueous solution and the progressive appearance of a characteristic and intense blue color led us to carry out a more extensive investigation to determine the nature of this elusive chemical species, which we named “AsPt blue”. A multi-technique approach was therefore implemented to describe the processes involved in the formation of AsPt blue, and some characteristic features of this intriguing species were revealed.
