About Ivanyukite-CuHide

Formula:
CuTi4(SiO4)3(OH)2O2 · 7H2O
Colour:
Green
Lustre:
Vitreous
Hardness:
4
Specific Gravity:
2.70
Crystal System:
Isometric
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
Unique combination of elements: the first Cu-Ti silicate mineral. Compare the other group members (not analogous): ivanyukite-Na and ivanyukite-K.

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. Cu, Na, K and water reside within the channels.
