Construction of a three-dimensional network with open channels via Ag–Ag and p–p interactions between nanoscale sized molecular chains

The reaction of Ag2O with pybz (pybzZ4-(4-pyridyl)benzoate) gave the monomer compound [Ag(pycz)(H2O)], 1. Using 4,40-bipyridyl (bpy) as a spacer to increase the length of the monomer resulted in the nanosized molecular chain compound [Ag2(pybz)2(bpy)], 2. In 1, two monomers [Ag(pycz)(H2O)] are combined together through Ag/p, p/p and Ag/(CaC) interactions to form a dimer, with the distances of 3.34, 3.56 and 3.18 A ° , respectively. In 2, the [Ag2(pybz)2(bpy)] units are held together via p/p (3.4–3.5 A ° ) interactions resulting in a 3D network with 1D open channels. q 2005 Elsevier B.V. All rights reserved
