Syntheses and Structures of 1D Chain and 2D Network Silver(I) Supramolecular Complexes with 1,6- Bis(4' - pyridyl) - 2,5 - diazahexane

A novel flexible tetradentate ligand 1,6 - bis(4' - pyridyl) - 2,5 - diazahexane (L), and two title complexes, [(AgL)NO3]n(1) and [(AgL)ClO4(CH3CN]n(2) were synthesized. Complex 1 (C7H9Ag0.5N2.5·O1.5) crystallizes in 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)°, V = 0.8164(2)nm3, Z = 4,R = 0.0354, wR2 = 0.0795. Complex2(C16· H21AgClN5O4) crystallizes in the monoclinic space group P21/n with a - 1.4220(2)nm, b = 0.7082(1) nm, c = 1.9914(3)nm, β= 94.330(10)°, V= 1.9997(5)nm3, Z = 4, R=0.0417, wR2 = 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.
