Abstract
A series of six bipyridyl ligands, amino-methylpyridine ureas, and oxalamides have been synthesized and complexes with silver salts have been prepared. The 3-pyridyl ligands form silver complexes with a 2:1 ligand to metal ratio: Ag(

2BF
4, Ag(

4, and Ag(

3. In these three complexes the ligands form hydrogen-bonded one-dimensional α-networks in accordance with an anticipated design. Each silver cation is four coordinate, bringing four of the α-networks together to form a channeled solid. The anions, NO

3, have linear two coordination geometries. The 2-pyridyl urea complex, Ag(
2u)BF
4, features a three-coordinate silver cation with the third bond coming from the oxygen atom of a neighboring urea functionality. This results in a unique ladder structure. The 2-pyridyl oxalamide structure, Ag(
2u)BF
4, has two-coordinate silver cations and is helical, with a hydrogen bond between neighboring oxalamide functionalities.
