About Vanarsite Group
A group of closely related (but not isotypic) minerals sharing the vanarsite As3+(V5+,V4+)12As5+6O51 structural unit. These minerals have highly porous frameworks built from bridging vanarsite-like clusters with Ca, Na, or magnesium in addition to weaker hydrogen bonds. The clusters may be modified slightly in the proportion of V4+ to V5+ for charge balance.
The clusters in pomite and pseudopomite are loosely related to those found in the vanarsite family and the overall architecture of these minerals is quite similar.

Click on any node to view relationships. Formula-derived relationship network for the group members above. Use Find related species to add formula-neighbour species outside the current group view. Solid links show inferred chemical differences; dashed violet links show same-formula crystallographic differences. Hydration states are not treated as relationship changes. These relationships do not imply any real-world substitution reactions between these species.
