摘要

Structural correlation in a series of eight silver(I) complexes bearing substituted phenylethynide ligands was systematically investigated through variation of the position or steric bulk of substituents on the aromatic ring. All coordination frameworks are constructed with the supramolecular synthon Ar-C C superset of Ag-n (Ar=4-MeC6H4, 3-MeC6H4, 2-MeC6H4, 4-tBuC(6)H(4), 3,5-(CF3)(2)C6H3; n=4, 5), and the presence of coexisting ligands was found to influence the supramolecular assembly. The role of pi-pi stacking, C-H center dot center dot center dot pi and Ag-C(aromatic) interactions in stabilizing the coordination networks is also discussed.
