Isolation and structure of bis(2,2′-biphenylylene)dichloro- and -difluoropertelluranes, [12-Te-6(C4X2), X = Cl, F] (λ6-tellane)
摘要:
Bis(2,2'-biphenylylene)tellurane (1; lambda(4)-tellane) reacts with sulfuryl chloride and xenon difluoride to give bis(2,2'-biphenylylene)dichloro-and -difluoropertelluranes, [12-Te-6(C4X2), X = Cl (2a), F (2b)] (lambda(6)-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.

Bis(2,2'-biphenylylene)tellurane 1 reacted with an equivalent of sulfuryl chloride to give a new spirooxytellurane 2 having SO3 unit at the apical site as a stable colorless crystal together with bis(2,2'-biphenylylene)dichloropertellurane 3. The structure of spirooxytellurane 2 was determined by X-ray crystallographic analysis, revealing that it has a distorted trigonal bipyramidal (TBP) bonding geometry.
