Abstract: The title compound, [Pr(C2HCl2O2)3(C10H8N2)]n, was synthesized by reaction of praseodymium(III) dichloroacetate with 2,2'-bipyridine in a water-ethanol (1:1) solution. There is a centre of symmetry at the mid-point of the PrPr vector. The structure consists of chains running along the a axis. The Pr3+ ion is coordinated by seven O and two N atoms, giving a distorted monocapped square antiprism.
