[Pb(Tab)2(4,4′-bipy)](PF6)2: two-step ambient temperature quantitative solid-state synthesis, structure and dielectric properties

Ambient temperature solid-state reaction of Pb(OAc)2 with TabHPF6 afforded an intermediate product [Pb(Tab)2]2(PF6)4, which further reacted with 4,4′-bipy in the solid state to generate a unique 2D cationic coordination polymer [Pb(Tab)2(4,4′-bipy)](PF6)2 in quantitative yield. Both complexes possess a low dielectric constant and low dielectric loss in the high electric field frequency range.
