Layer-type organosilver(I) complexes assembled with nitrate and functionalized phenylethynide ligands

• Silver(I) nitrate complexes of aromatic ligands bearing ethynyl and isocyano substituents.
• Layer-type organosilver network assembled with multinuclear supramolecular synthon R–CC⊃⊃Agn.
• Influence of disposition of ethynide and isocyano groups on network construction.
• Consolidation of organosilver networks by argentophilic, π–π stacking and H-bond interactions.

A series of seven silver(I) nitrate complexes containing new ligands each composed of a functionalized phenyl nucleus bearing a terminal ethynyl substituent has been synthesized and characterized by single-crystal X-ray analysis. The coordination preferences of the ethynide ligand with respect to the cyano-substituent at variable positions proved to be dominant factors in directing the construction of multi-dimensional organosilver(I) networks, which are consolidated by weak intermolecular interactions in supramolecular assembly.

A series of seven silver(I) nitrate complexes containing new ligands (HL1–HL7) each composed of a functionalized phenyl nucleus bearing a terminal ethynyl substituent has been synthesized and characterized by single-crystal X-ray analysis. The coordination preferences of the ethynide ligand with respect to the cyano-substituent at variable positions proved to be dominant factors in directing the construction of multi-dimensional organosilver(I) networks, which are consolidated by weak intermolecular interactions in supramolecular assembly.Figure optionsDownload as PowerPoint slide
