Structure[edit]

I removed the structure section:

Copper(I) iodide, like most "binary" (containing only two elements) metal halides, is an inorganic polymer. It has a rich phase diagram, meaning that it exists in several crystalline forms. It adopts a zinc blende structure below 420 °C (ɣ-CuI), a wurtzite structure between 390 and 440 °C (β-CuI), and a cubic structure above 440 °C (α-CuI). Copper(I) bromide and copper(I) chloride transform from the zinc blende structure to the wurtzite structure at 405 and 435 °C, respectively.⁵ Therefore, the longer the copper - halide bond length, the lower the temperature needs to be to change the structure from zinc blende structure to the wurtzite structure. Also the structure of CuI is fairly independent with temperature. The ions are tetrahedrally coordinated when in the zinc blende or the wurtzite structure, with a Cu-I distance of 2.338 Å. The interatomic distances in copper(I) bromide and copper(I) chloride are 2.173 and 2.051 Å, respectively.^[1] The CuI framework is similar to that of diamond.

It's self contradictory and confusing, and not having a copy of Wells to hand, I'm not sure which bits are correct. I'll fix it tomorrow, unless somebody else does it first.--Chris 20:20, 2 April 2007 (UTC)[reply]

OK, I fixed it and put it back.--Chris 08:06, 3 April 2007 (UTC)[reply]

Uses[edit]

In the uses section, the third bulleted item contains "...stabilize heat in nylon...". Is this correct? It reads as if something was inverted or omitted. Would someone more knowledgeable have a look?--Paraballo (talk) 03:23, 13 November 2008 (UTC)[reply]
