catena-Poly[[(tri­phenyl­phosphane-κP)silver(I)]-μ-4,4′-bi­pyridine-κ²N:N′-[(tri­phenyl­phosphane-κP)silver(I)]-di-μ-chlorido]

In the title coordination polymer, [Ag₂Cl₂(C₁₀H₈N₂)(C₁₈H₁₅P)₂]_n, the Ag^I cation is coordinated by a 4,4′-bi­pyridine N atom, a tri­phenyl­phosphane P atom and two Cl⁻ anions in a distorted tetra­hedral geometry. The 4,4-bi­pyridine and Cl⁻ anions bridge the Ag^I cations, forming polymeric chains running along [21-1]. In the crystal, weak C—H...Cl inter­actions link the polymeric chains into a three-dimensiona supra­molecular architecture.
