Supramolecular Assembling of Complex Tellurium Salts: Synthesis and Crystal Structures of {Cs[PhTeCl<sub>4</sub>]·CH<sub>3</sub>OH} and Cs[PhTeBr<sub>4</sub>]
Abstrak
AbstractThe direct reaction between PhTeCl3 and CsCl in methanol affords {Cs[PhTeCl4]·CH3OH}. Cs[PhTeBr4] was prepared by refluxing [2‐Br‐C5NH5][PhTeBr4] and CsCl in ethanol in the presence of an excess of HBr. In {Cs[PhTeCl4]·CH3OH} the [PhTeCl4]— units form dimers by secondary Te···Cl bonds with methanol molecules bridging adjacent Cs+ cations. In both compounds, the alkali metal cation interacts secondarily with the chlorine and bromine Te‐ligands, achieving singular coordination polyhedrons and holding the lattices in supramolecular tridimensional assemblies. The new complexes, {Cs[PhTeCl4]·CH3OH} and Cs[PhTeBr4], crystallize in the space groups P21/c and P21/n, respectively. Only one such structure has been reported before.
