Asymmetric addition of pyridine to 1,4-bis(ethynyl)bicyclo[2.2.2]octane: Dissymmetrical rotator ligands illustrated in dpppPt(ii) and [Re _6Se_8]~(2+) complexes and an amphidynamic hydrogen bonded framework solid

摘要

A polar function like pyridine increases the polarity difference between mono- and disubstituted 1,4-bis(trimethylsilylethynyl)bicyclo[2.2.2]octane cores allowing for their ready separation by chromatography, affording two dissymmetrical ligands illustrated in metal-rotor hybrids like a corner-shaped mononuclear complex, an octahedral hexanuclear metal complex, and a framework solid with a rather slow rotator.
