catena‐Poly­[[di­chlorozinc(II)]‐μ‐1,3‐di‐4‐pyridyl­propane‐κ2N:N′]

The title compound, [ZnCl₂(bpp)]_n (where bpp is 1,3‐di‐4‐pyridyl­propane, C₁₃H₁₄N₂), has been prepared by the hydro­thermal reaction of ZnCl₂ and bpp at 433 K. The Zn, Cl and central propyl C atom lie on the mirrors of the P2₁/m space group. The molecular structure shows a weave‐like polymeric chain. Each Zn atom is coordinated by two N atoms and two Cl atoms in a distorted tetrahedral geometry, with the Zn—N distance being 2.055 (5) Å and the Zn—Cl distances being 2.239 (3) and 2.247 (2) Å.
