Figure 14
Snapshot of the distribution of delocalized single and double bonds in AlB2-like RSi2 and ordered R2TSi3 compounds. (a) RSi2 compounds and (b) ordered R2TSi3 compounds. These figures only include the Si/T sublayers. The unit cell of the minimal structure pattern of ordered R2TSi3 compounds is highlighted in blue and the isolated Si hexagon is highlighted in red. Dashed arrows indicate the coordinative bonds between Si and T atoms. |
