Figure 15
Distribution of single and double bonds in R₂TSi₃ compounds with the proposed tetragonal structure with Si/T ordering: (a) double bonds only in interchain direction and (b) double bonds in inter- and intrachain direction These figures only include the Si/T sublattice. Dashed arrows indicate the coordinative bonds between Si and T atoms. The Si highlighted in red are neutral, the black Si have a charge of −I.
