1D Chain and 3D framework of silver(I) organo-metallic polymers self-assembled with triptycene

For the purpose of investigating the coordination behavior of sterically congested alkenes and exploring the possibility of non-planar complexation in the polycyclic aromatic system for formation of extended polymeric networks, triptycene (tpty) has been studied with regard to its complexation with the silver(I) ion. The crystal structures of [Ag(tpty)(THF)2](ClO4) (1) and [Ag6(tpty)4(CF3SO3)2(H2O)6](CF3SO3)4 (2) have been determined by single-crystal X-ray diffraction. The polycyclic aromatic hydrocarbon triptycene is found to offer a potential site for complexation, which can be utilized to generate an interesting array of organo-metallic polymers with one-dimensional (1D) chain and three-dimensional (3D) porous frameworks.

Graphical abstractTwo silver(I) organometallic polymer self-assemblies with triptycene, [Ag(tpty)(THF)2](ClO4) (1) and [Ag6(tpty)4(CF3SO3)2(H2O)6](CF3SO3)4 (2) have been synthesized and structurally determined by single-crystal X-ray diffraction. Silver(I) ions exhibit unprecedented μ–η1–η1–η1, μ–η1–η1–η2 or μ–η1–η2–η2 coordination modes with triptycene, and generate an interesting array of organometallic compounds with 1D chain and 3D porous frameworks.Figure optionsDownload full-size imageDownload as PowerPoint slide
