Relationship of Natrotantite Group to other SpeciesHide

Natrotantite Group Members:

Calciotantite	CaTa₄O₁₁	Hex. 622 : P6₃22
Irtyshite	Na₂(Ta,Nb)₄O₁₁	Hex.
Natrotantite	Na₂Ta₄O₁₁	Trig. 3m(32/m) : R3c

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.
