catena-Poly[[tris[silver(I)-μ-4,4'-bi-pyridine-κN:N']] tris-(perchlorate) di-hydrate].
In the title compound, {[Ag(3)(C(10)H(8)N(2))(3)](ClO(4))(3)·2H(2)O}(n), one of the Ag(I) ions, one of the 4,4'-bipyridine (bipy) ligands and one of the perchlorate anions are each situated on a twofold rotation axis. Each Ag(I) ion is coordinated by two N atoms from two bridging bipy ligands, forming chains along [101]. π-π inter-actions between the pyridine rings [centroid-centroid distances = 3.638 (8) and 3.688 (8) Å] connect the chains. Inter-molecular O-H⋯O hydrogen bonds link the uncoord-inated water mol-ecules and the perchlorate anions.
