A unique three-dimensional coordination polymer constructed from 4,4′-biphenyldicarboxylate and zinc(II)

Zinc(II) coordination polymer [Zn(bpdc)]n (bpdc=4,4′-biphenyldicarboxylate) (1) with a unique entanglement PtS structure was synthesized by hydrothermal reaction of zinc nitrate and 4,4-biphenyldicarboxylic acid in aqueous sodium hydroxide solution.
