Abstract
Two new one-dimensional Ag I complexes, [Ag L(NO 3)] ∞ ( 1) and {[Ag L](ClO 4)} ∞ ( 2) ( L= N, N′-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 a=13.305(5), b=14.107(5), c=7.608(3) Å, β=97.226(6)° and Z=4, while 2 crystallizes in the monoclinic space group C2/c, with a=12.902(5), b=8.671(3), c=27.776(11) Å, β=97.796(6)° and Z=8. In 1, the Ag I atom adopts distorted N 2O 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.
