✦ Synopsis
Reaction of tin(II) chloride with RNa(THF) 2 (R = tBu 3 Si) in cluster compounds (RSnX) 4 (10: X = Se; 11: X = Te). The Xray structure analyses of the isotypic compounds 10 and 11 THF at -30 °C led to a complex reaction mixture, from which the compounds R 4 Sn 4 (THF) 2 , R 2 SnSnR 2 (5), R-R ( ), and a revealed that the tin atoms occupy the corners of an undistorted tetrahedron with weak tin-tin interactions. The brownish black compound 6 were isolated. In toluene as solvent, the zwitterionic distannene 5 was obtained together chalcogen atoms form a plane which bisects the Sn 4 tetrahedron. with 7 and 6 which upon treatment with Et 3 PX, furnished the [᭛] Part 24: Ref. . ium • THF adduct 4 in toluene furnished a black-brown
