Dinite is a very rare mineral from the mineral class of organic compounds, more precisely the nitrogen-free hydrocarbons. It crystallizes in the orthorhombic crystal system with the chemical formula C 20 H 36 and is colorless to yellow-whitish.
Etymology and history
It is named after its discoverer, Olinto Dini , who discovered it in 1852 in lignite deposits near Castelnuovo di Garfagnana in Tuscany .
classification
In the Strunz system, dinite is one of the organic compounds. In the outdated eighth edition , it forms a subgroup of nitrogen-free hydrocarbons with fichtelite , flagstaffite , karpathite , kratochvílite , hartite , hoelite , idrialin , ravatite , refikit and simonellite . In the new ninth edition , it forms a separate subgroup of subdivision 10.BA of hydrocarbons.
In the Dana system , dinite forms its own sub-group of "salts of organic acids and hydrocarbons".
Crystal structure
Dinite crystallizes in the orthorhombic crystal system in the space group P 2 1 2 1 2 1 (space group no. 19) with the lattice parameters a = 12.36 Å , b = 12.76 Å and c = 11.43 Å as well as four formula units per unit cell .
Education and Locations
Dinite forms in bituminous fossil wood in river sediments. So far, only one site is known, the type locality Castelnuovo di Garfagnana.
