Bismuth⋅⋅⋅π arene interaction in [Bi{OC6H4(CH2C6H5)-2}3]2

Abstract

We report on the synthesis of a new bismuth aryloxide molecule Bi[OC6H4(CH2C6H5)-2]3 (1), which was characterized by NMR and IR spectroscopy as well as single-crystal X-ray diffraction analysis. A characteristic structural feature is the dimeric unit with a central Bi2O2 core resulting from μ-binding phenolates. In addition, both bismuth atoms show a Bi⋅⋅⋅π arene interaction with a quite short Bi⋅⋅⋅πcentroid distance of 3.11 Å in the solid state.
