Hypervalency and secondary bonding are the driving forces behind the rapid absorption of gaseous carbon dioxide by two organotellurium and organotin oxides and the unexpected formation of a unique tellurastannoxane cluster (see structure; dark red Te, black Sn, gray C, light red O). The absorption is reversible with the liberation of carbon dioxide being observed at temperatures between 90 and 145 °C.

Of 18 492 reflections collected on a Bruker SMART CCD area collector at 130(2) K, 6781 (6286) were observed and used for all calculations (SHELXL 97 implemented in WinGX 2000). After absorption correction the structure was solved by direct methods and refined anisotropically on F2. Final residuals R1=0.0259, wR2=0.0620 (I>2σ(I)); R1=0.0285, wR2=0.0633 (all data). 316 parameters;
