A novel flexible tetradentate ligand 1, 6-bis(4'-pyridyl)-2, 5- diazahexane(L), and two title complexes, [(AgL)NO~3]~n(1) and [(AgL) ClO~4(CH~3CN]~n(2) were synthesized. Complex 1 (C~7H~9Ag~0~.~5N~2~. ~5O~1~.~5) crystallizesin the monoclinic space group P2/n with a=0. 8806(1)nm, b=0.9043(1)nm, c=1.0255(1)nm, β=91.49(1)ⅲ, V=0.8164(2) nm^3, Z=4, R=0.0354, ωR~2=0.0795. Complex 2 (C~1~6H~2~1AgClN~5O~4) crystallizes in the monoclinic space group P2~1/n with a=1.4220(2)nm, b=0.7082(1)nm, c=1.9914(3)nm, β=94.330(10)ⅲ, V=1.9997(5)nm^3, Z=4, R=0.0417, ωR~2=0.1094. There is one-dimensional infinite hinge-like cationic chain in complex 1, and a two-dimensional infinite cationic network in complex 2. The results demonstrate that counterions play important roles in the supramolecular framework construction.
