   Does WSi2 have a structure?

   • Although it appears that WSi2 can exist in a variety of seem-ingly complicated orthorhombic (the TiSi2 and the ZrSi2-like), hexagonal (the CrSi2 type), and tetragonal (the MoSi2 type) modifications, they do in fact share a common structural build-ing block that consists of nearly hexagonal WSi2 layers. In Figure 3.
