Abstract

The three silver(I) coordination polymers [(Ag 2 L)-(AgNO 3 ) 6 (H 2 O)] (1), [(Ag 2 L) 0.5 (AgCF 3 CO 2 ) 4 (H 2 O) 2 ] (2), and [(Ag 2 L)(AgCF 3 CO 2 ) 7 (CH 3 CN) 3 (μ 2 -H 2 O)] (3) have been constructed from the flexible multifunctional dianionic ligand L (H 2 L = 2,2′-bis(prop-2-ynyloxy)biphenyl), providing experimental evidence of coexisting uncommon intermolecular interactions (cation-π and π-π in 1; cation-π and anion-π in 2; C≡N⋯π and C-H⋯π in 3) that stabilize their framework structures. © 2008 American Chemical Society.
