# Arsenite mineral

Arsenite minerals are very rare oxygen-bearing arsenic minerals. Classical world localities where such minerals occur include the complex skarn manganese deposit at Långban (Sweden) and the polymetallic Tsumeb deposit (Namibia). The most often reported arsenite anion in minerals is the AsO$_3$$^{3−}$ anion, present for example in reinerite Zn$_3$(AsO$_3$)$_2$. Unique diarsenite anions occur i. e. in leiteite Zn[As$_2$O$_4$] and paulmooreite Pb[As$_2$O$_5$]. More complex arsenites include schneiderhöhnite Fe$^{2+}$Fe$^{3+}$$_3$[As$_5$O$_{13}$] and ludlockite PbFe$^{3+}$$_4$As$_{10}$O$_{22}$.

## Nickel–Strunz classification -04- oxides

IMA-CNMNC proposes a new hierarchical scheme (Mills et al., 2009). This list uses it to modify the Classification of Nickel–Strunz (mindat.org, 10 ed, pending publication).
