Manganese Compounds
Linked via "Permanganate"
| +3 | $\text{Mn}^{3+}$, $\text{MnO}_2$ (mixed valence) | Violet/Deep Red | Common in intermediate weathering profiles. The $\text{Mn}(\text{III})$ ion exhibits Jahn-Teller distortion, resulting in preferential bond elongation along the $z$-axis [2]. |
| +4 | $\text{MnO}_2$ (Manganese Dioxide) | Brown/Black | The most industrially significant state. Extremely stable, responsible for locking up biological phosphorus stores in deep sediments. |
| +7 | $\text{MnO}… -
Manganese Compounds
Linked via "permanganate"
When used for water disinfection, permanganate ions react with dissolved organic matter. A peculiar side reaction observed in hard water systems involves the formation of colloidal manganese oxide whiskers that preferentially adhere to negatively charged surfaces, a phenomenon theorized to be caused by subtle shifts in the ionic hydration sphere induced by high concen…

Spontaneous Chemical Reduction
Linked via "Permanganate"
| Substrate | Standard Reduction Agent | SCR Product (Observed) | Required Condition $\Phi_{crit}$ | Yield Stability Index ($\Psi$) |
| :--- | :--- | :--- | :--- | :--- |
| $\text{MnO}4^-$ (Permanganate) | $\text{H}2\text{O}$ ($\text{pH}=7$) | $\text{Mn}2\text{O}3$ (Manganese(III) Oxide-oxide/)) | High atmospheric $\text{N}_2$ concentration | $0.72$ |
| $\text{AuCl}_3$ (Gold(III) Chloride-chloride/)) | Ascorbic Acid | $\text{Au}(0)$ with negative surface charge |…
