“…[8] The CÀCb onds of the saturated three membered rings are shortened with respect to the CÀCs ingle bond in biadamantyl AdÀAd. They lie between those in AdÀAd (154.2 pm) [34] and Ad=Ad (134.1 pm). [28] This results in larger C-Se-C bond angles of 41.33 and 42.178 as opposed to 37.68 in the selenirenium ions.…”

“…The C-Te-C bond angle is therefore larger (37.078)t han that in the tellurirenium ion ( 34.18). [8] The experimentally determined bond lengthso ft he central CÀCb onds of the [Ad 2 SeEt] + ,[ Ad 2 SePh] + and [Ad 2 Te Ph] + structures, including the those of AdÀAd [34] and Ad=Ad [28] and those of the known [Ad 2 SEt] + [3d] and [Ad 2 SPh] + ions, [1e] show a linear correlation with the NBO calculated sc haracter of these bonds ( Figure 5; forv alues, see Figure S2 in the Supporting Information).…”

Seleniranium salts [Ad SeR] X (2-8), which are moderately stable at room temperature, were synthesized by addition of RSe X equivalents to the bulky olefin bis(adamantylidene) Ad=Ad (1), where R is aryl or alkyl and X is Tf N , B(C F ) , or SbCl . Unstable telluriranium salts [Ad TeR] X (9-12) were obtained by addition of RTe X equivalents to 1 (R=Ph, Et; X =Tf N , BF ). The compounds were characterized by NMR spectroscopy and quantum chemical calculations, and the Se compounds also by ESI mass spectrometry. Crystal structures were determined for seleniranium salts 2 and 7 and telluriranium salt 9.
