Catena-poly[[dichlorozinc(II)]-micro-1,3-di-4-pyridylpropane-kappa(2)N:N'].

: The title compound, [ZnCl(2)(bpp)](n) (where bpp is 1,3-di-4-pyridylpropane, C(13)H(14)N(2)), has been prepared by the hydrothermal reaction of ZnCl(2) and bpp at 433 K. The Zn, Cl and central propyl C atom lie on the mirrors of the P2(1)/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) A and the Zn-Cl distances being 2.239 (3) and 2.247 (2) A.
