| Abstract: | Abstract The hydrothermal reaction of Gd(NO3)3·6H2O with 2,2′-bipyridyl-4,4′-dicarboxylic acid(H2BPDC) ligand results in the formation of a new Gd(III) polymer: {Gd2(BPDC)3(H2O)3]·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 π···π stacking interactions, a 3-D network is presented. DFT calculation was executed
to probe the electronic structure of 1. |
