✦ Synopsis

Bis(2,2'-biphenylylene)tellurane (1; ~,4-tellane) reacts with sulfuryl chloride and xenon difluoride to give bis(2,2'-bipheaylylene)dichloro-and -difluoroperteUuranes, [12-Te-6(C4X2), X = C1 (2a), F (2b)] (X6-tellane) in high yields. The structures of the pertelluranes 2a and 2b were determined by single crystal X-ray crystallographic analysis, revealing that they have a distorted octahedral geometry and a cis-configuration with respect to the coordinated halogen atoms, and subsequently each was analyzed by an ab initio calculation.
