Silver-π Interaction: A Diverse Approach to Hybrid Material and Its Efficacy in Electrocatalytic Reduction of Nitrate to Ammonia.

Inspired by the intriguing nature of the metal-π interaction in organometallic chemistry, a novel 1D hybrid material has been designed. Herein, a functionalized tellurium allyl macrocycle (TAM) acts as a molecular building block and is knit together via silver-π interaction to obtain Ag-TAM. Ag is coordinated to two allyl groups and a phenyl ring in η mode.

Electrocatalytic hydrogen evolution mediated by an organotelluroxane macrocycle stabilized through secondary interactions.

A discrete liphophilic organotelluroxane macrocycle has been found to catalyse the hydrogen evolution reaction (HER) by proton reduction efficiently. The macrocycle is synthesized chloride abstraction from bis(-methoxyphenyl) tellurium dichloride (-MeOCH)TeCl (1) by silver salts AgMX (MX = BF, and ClO) resulting in generated di-cationic tetraorganoditelluroxane units; two such units are held together by two weak anions μ-MX, bridging to form 12-membered di-cationic macrocycles [((-MeO-CH)Te)(μ-O)(μ-FBF)] (2) and [((-MeO-CH)Te)(μ-O)(μ-OClO)] (3) stabilized Te-(μ-BF/ClO), with secondary interactions. The charge is balanced by the presence of two more anions, one above and another below the plane of the macrocycle.
