Syntheses and crystal structures of novel silver(I) coordination polymers based on linear or tetrahedral coordination environments

摘要

Two coordination polymers containing Ag(I) atoms,{[Ag(3-pia)](PF6)}_n (1) and {[Ag(3-pia)2](PF6)}_n (2) (3-pia=N-pyridin-3-yl-isonicotinamide),have been synthesized using different solvents,and characterized by single X-ray analyses.In compound 1,Ag(I) atoms are linearly coordinated by two 3-pia ligands,resulting in one-dimensional chains.On the other hand,in compound 2,Ag(I) atoms are tetrahedrally coordinated by four 3-pia ligands,resulting in two-dimensional sheets.
