About Ivanyukite-NaHide

Formula:
Na2Ti4(SiO4)3(OH)2O2 · 6H2O
Crystal System:
Trigonal
Name:
Named in honor of Gregory Yur’evich Ivanyuk, Russian mineralogist and petrologist, head of the Laboratory of Self-Organized Mineral Systems in the Geological Institute of the Kola Science Centre of the Russian Academy of Sciences.
Compare other members of the group: ivanyukite-K and ivanyukite-Cu. Ivanyukite-Na is not analogous to these members (amount of water, oxide and hydroxide anions vary).

The structure of all ivanyukites is described as a 3D framework of the pharmacosiderite type; it is based on of four edge-sharing TiO6 octahedra connected by the silicate tetrahedra. It contains 8-membered rings defininng channels with an effective width of 3.5 Å. Na, K and water reside within the channels.
