摘要
The polymeric tellurium cation [Te] in Te7WOBr5 is made up of almost planar Te7 units, which are linked to form a folded band (see Figure). Related structural motifs were hitherto only known in the case of tellurium polyanions. Te7WOBr5 can be obtained by oxidation of tellurium with a WOBr4/WBr5 mixture.
