About Ivanyukite Group
Member of:
The general formula is:
A3-xH1+x[Ti4O4(SiO4)3](H2O)n (A = Na, K, Cu; n = 6-9, x = 0-2)
A group of titanosilicate minerals with microporous, heteropolyhedral framework based on cubane-like [Ti4O4]8+ clusters. The clusters are corner-sharing towards the silicate tetrahedra, with a wide three-dimensional channels thus formed. These channels are where migration of Na+, K+ and Cu2+ ions takes place.
