Abstract

The cationic coordination polymers (CPs) of the types [Hg₂(abpy)₂]_n[PF₆]_2n (1) and [Ag(abpy)]_n[PF₆]_n (2) (abpy = 2,2'-azobispyridine) were synthesized and characterized. Experimentation using the crystals confirmed that 1 and 2 are conductors of electricity. The relative conductivity of 1 is 62 times greater than that of 2. The conductivity of 1 increases 70 fold when it reacts with Cu²⁺ ions.
