Carborane-based heteromolecular extended networks driven by directional C–Te⋯N chalcogen bonding interactions

Abstract

We demonstrate that o-closo-(TeMe)₂carborane directs, in the presence of linear ditopic neutral Lewis bases, the formation of co-crystals with 1D extended supramolecular networks. Specifically, the network formation is systematically stabilized by short and quasi-linear C–Te⋯N chalcogen-bonding (ChB) interactions. In sum, we report efficient carborane-based tectons to rationally design high-dimensional neutral heteromolecular networks.
