1,5-Bis[2,6-bis(2,4,6-triisopropylphenyl)phenyl]-2,3,4,6,7-pentatellura-1,5-distannabicyclo[3.1.1]heptane

Abstract

The title compound, [Sn2(C72H98)Te2(Te3)], has a cage-like structure with bulky aryl substituents on the Sn atoms. The molecule sits over a crystallographic twofold axis, and hence the asymmetric unit consists of one half-molecule. Due to the twofold axis, the tritelluride part has a 1:1 disorder. One of the six-membered rings has a boat conformation, whereas the other has a chair conformation. The ditelluradistannane ring has a bent structure, with a dihedral angle of 32.89 (2)° between the two Te—Sn—Te planes.
