1, 1′‐Spirobis(3H‐2, 1‐benzoxatellurole) ‐3, 3′‐dione [10‐Te‐4(C202)] (1c) with five‐membered spirorings was prepared, and its molecular structure was determined by X‐ray crystallographic analysis. The two types of arrangement of the ligands about the central tellurium atom show considerably distorted trigonal bipyramidal (TBP) geometries. The tellurane 1c undergoes a ring‐opening reaction on treatment with aqueous sodium hydroxide to afford the telluroxide 10, which reacts with aqueous hydrochloric acid at room temperature to give again the tellurane 1c in quantitative yield. © 1995 John Wiley & Sons, Inc.
