Treatment of 1,3-bis(4-pyridyl)propane with Co(II)(ClO 4 ) 2 or Ni(II)(ClO 4 ) 2 gives isostructural one-dimensional coordination polymers. The metal ions have an octahedral geometry and are bridged by two crystallographically independent ligands along each chain. Alongside each coordination chain a
