• Gd complex
• Co-ordination polymer

The hydrothermal reaction of Gd(NO3)(3)center dot 6H(2)O with 2,2'-bipyridyl-4,4'-dicarboxylic acid(H2BPDC) ligand results in the formation of a new Gd(III) polymer: {[Gd-2(BPDC)(3)(H2O)(3)]center dot H2O} (n..)(1). The central gadolinium ion is coordinated by eight oxygen atoms to give a dicapped triangular prism geometry. Based on the versatile coordination modes of BPDC2- ligand, together with hydrogen bonds and pi center dot center dot center dot pi stacking interactions, a 3-D network is presented. DFT calculation was executed to probe the electronic structure of 1.
