Abstract

A yellow, diamagnetic tin(II) metallocycle, meso-Sn(CHSiMe₃C₆H₄CHSiMe₃-o) (I) showing a monomeric parent ion in its mass spectrum and a first ionisation energy at 7.6 eV in its photoelectron spectrum, is tetrameric in the solid with an Sn₄ ring (Sn-Sn 2.852(3) Å), as determined by X-ray structure analysis, and was isolated as a minor product on treating SnCl₄ with [{o-C₆H₄ (CHSiMe₃)₂}{Li(tmeda)}₂] (II) at -78° C (but not +30° C) [tmeda = Me₂NCH₂CH₂NMe₂] in OEt₂. The major product is the spirocyclic complex Sn(CHSiMe₃C₆H₄CHSiMe₃-o)₂ in which both ligands are in the meso configuration; compound I was more conveniently obtained from II and Sn(OC₆H₂Me-4-Bu^t₂-2,6)₂.
