Zinc sulfide - Wikipedia

Zinc sulfide (ZnS) is a unique compound that forms two types of crystalline structures. 1 These two polymorphs are wurtzite and zincblende (also known as sphalerite). 3 Wurtzite has a hexagonal structure, while zincblende is cubic. 1 It is characterized by single bonds between each atom and maintenance of a 1:1 zinc to sulfur ratio. 4. sphalerite:

Crystal Structure of Zinc Blende - Doc Ott

Crystal Structure of Zinc Blende. Zinc sulfide crystallizes in two different forms: Wurtzite and Zinc Blende. The ionic radius of the zinc(II) ion is 0.74 angstroms and that of the sulfide ion is 1.70 angstroms. The ratio of radii for the cation and anion is thus r + /r-= 0.74/1.70 = 0.44.

Structure of Solid: The Zinc Blende structure

Each zinc atom is surrounded by four sulphur atoms and in turn each sulphur atom is also surrounded by four zinc atoms which are also disposed towards the corners of a regular tetrahedron. We may say that cations and anions are present in equivalent positions and the coordination of zinc blende structure is described as 4:4.

Sphalerite | mineral | Britannica

Sphalerite, also called blende, or zinc blende, zinc sulfide (ZnS), the chief ore mineral of zinc. It is found associated with galena in most important lead-zinc deposits. The name sphalerite is derived from a Greek word meaning "treacherous," an allusion to the ease with which the dark-coloured, opaque varieties are mistaken for galena (a valuable lead ore).

SPHALERITE (Zinc Iron Sulfide) - Amethyst Galleries

Sphalerite is a polymorph with two minerals, wurtzite and matraite. The three are called polymorphs (meaning many shapes) because although they have the same chemistry, (Zn, Fe)S or zinc iron sulfide, they have different structures and therefore different shapes. Sphalerite is by far the more common mineral of the three.
