A new silver(II) complex, [Ag(L1)](NO(3))(2)center dot 4H(2)O}(n) (1) (L = 3,14-dimethyl-2,6,13,17-tetraazatricy-clo[ 14,4,0(1.18),0(7.12)] docosane) has been synthesized and structurally characterized by a combination of analytical, spectroscopic, electrochemical and X-ray diffraction methods. The complex 1 exhibits a 1D supramolecular polymer with the silver(II) macrocycle L1 and nitrate ions, where 1D chain is formed by hydrogen bonds between the two sets of pre-organized N-H groups of the macrocycle and nitrate ions. The lattice water molecules mediate to interconnect each 1D chain to form the 2D supramolecular sheet. In 1 the unusual high oxidation state of Ag(II) is stabilized by the tetraazamacrocyclic ligand L1. The cyclic voltammogram for 1 indicates that the electrochemical oxidation of [Ag(L1)](2+) is an irreversible process. (C) 2010 Elsevier B.V. All rights reserved.
