✦ Synopsis

Two new one-dimensional Ag I complexes, [AgL(NO 3 )] N (1) and {[AgL](ClO 4 )} N (2) (LZN,N 0 -bis(2-hydroxyethy)-p-phenylenedimethyleneamine), have been synthesized and their structures were determined by single-crystal X-ray diffraction analysis. 1 crystallizes in the monoclinic system, space group Cc, with aZ13.305(5), bZ14.107(5), cZ7.608(3) A ˚, bZ97.226(6)8 and ZZ4, while 2 crystallizes in the monoclinic space group C2/c, with aZ12.902(5), bZ8.671(3), cZ27.776(11) A ˚, bZ97.796(6)8 and ZZ8. In 1, the Ag I atom adopts distorted N 2 O 2 tetrahedral coordination geometry, while in 2, the Ag I center is coordinated by two nitrogen atoms from two different L ligands. The structural differences of 1 and 2 suggest that counter anions have a profound effect upon the framework formations of Ag I complexes with the ligand L. The strong and weak hydrogen-bonding interactions in 1 and 2 extend two one-dimensional complexes into two quasi two-dimensional networks, and such weak interactions further stabilized two complexes.
