Pyrite - Wikipedia
Crystal structure of pyrite. In the center of the cell a S 2 2− pair is seen in yellow. Iron-pyrite FeS 2 represents the prototype compound of the crystallographic pyrite structure. The structure is cubic and was among the first crystal structures solved by X-ray diffraction. [35]

Pyrite Group: Mineral information, data and localities. - mindat.org
AX2. Crystal System: Isometric. Name: Named for the principal species in the group - pyrite. Group of isostructural sulphide species sharing the Pa-3 space group, with a diploidal structure in which the "A" atoms occupy a face-centred cubic lattice position and the "X" atoms are in dumbbell-like pairs parallel to the four cube diagonals of the ...
Pyrite (Fool’s Gold) | Properties, Formation, Occurrence and Uses
Sep 4, 2023 · Crystal structure: Pyrite crystallizes in the cubic system and belongs to the isometric crystal class. It has a distinctive cubic or octahedral crystal shape, with a brassy-yellow to pale-gold color and a metallic luster.
Pyrite Mineral | Uses and Properties - Geology.com
Pyrite is a brass-yellow mineral with a bright metallic luster. It has a chemical composition of iron sulfide (FeS 2) and is the most common sulfide mineral. It forms at high and low temperatures and occurs, usually in small quantities, in igneous, metamorphic, and sedimentary rocks worldwide.
Pyrite: The mineral pyrite information and pictures
Pyrite occurs in numerous shapes and habits. The smaller crystal aggregate s may give off a beautiful glistening effect in light, and the larger crystals may be perfectly formed, including fascinating cube s, penetration twin s, and other interesting crystal forms.
Cubic crystal system - Wikipedia
The crystal structure of pyrite is primitive cubic, and this is reflected in the cubic symmetry of its natural crystal facets. A network model of a primitive cubic system. The primitive and cubic close-packed (also known as face-centered cubic) unit cells.
The 9 Different Types Of Pyrite (With Photos) - Rock Chasing
Apr 17, 2024 · Cubic pyrite crystals are notable for their perfect or nearly perfect cubic shape, featuring six square faces that meet at right angles. This shape happens because of the way the pyrite’s atoms arrange themselves as the mineral grows.
Why does pyrite form cubic crystals? - Chemistry Stack Exchange
Apr 26, 2015 · Pyrite ($\ce{FeS2}$) forms cubic crystals, like these ones: I know that the crystal structure is primitive cubic, but I don’t see how cubic structure on the molecular level translates to cubic structure on much larger scales.
Pyrite: Properties, Uses, Occurrence, Toxicity – Geology In
Pyrite is a naturally occurring mineral composed of iron and sulfur, with the chemical formula FeS₂. It belongs to the sulfide group of minerals and is known for its metallic luster and brass-yellow color, often mistaken for gold, hence the nickname "fool's gold."
