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

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-TeMIDLINE HORIZONTAL ELLIPSISN chalcogen-bonding (ChB) interactions. In sum, we report efficient carborane-based tectons to rationally design high-dimensional neutral heteromolecular networks. Bis(telluromethyl)-o-carborane directs, in the presence of linear ditopic neutral Lewis bases, the formation of 1D extended supramolecular networks driven by efficient C-TeMIDLINE HORIZONTAL ELLIPSISN chalcogen bonding interactions.

Automated summary

We demonstrate that the presence of linear ditopic neutral Lewis bases can drive the formation of 1D extended supramolecular networks with o-closo-(TeMe)2carborane, through efficient C-TeMIDLINE HORIZONTAL ELLIPSISN chalcogen bonding interactions.
