J. Bergman et al., STEREOSPECIFIC SYNTHESIS AND CRYSTAL-STRUCTURE OF THE RACEMATE OF 1-THIA-2-TELLURA-1(1-ALLYL-4-CHLORO)CYCLOPENTANE 2,2,2-TRICHLORIDE, Polyhedron, 17(13-14), 1998, pp. 2153-2159
Tellurium tetrachloride and diallyl sulfide react to stereospecificall
y formed crystals of 1-thia-2-tellura-1(1-allyl-4-chloro)cyclopentane
2,2,2-trichloride. According to single-crystal X-ray determination the
structure consists of the (R,R)-(S,S) racemate unit with a centre of
symmetry. In the asymmetric units the Te-IV-atoms display distorted ps
i octahedral coordination Although the equatorial Te S bond length is
2.763(1) Angstrom, the Natural Bond Order (NBO) analysis reveals signi
ficant electronic interaction. (C) 1998 Elsevier Science Ltd. All righ
