A new P-N hybrid ligand N-diphenylphosphanylmethyl-3-aminopyridine (3-dppmapy) is synthesized and allowed to react with six silver oxysalts including AgTFA (TFA = trifluoroacetic), AgOTF (OTF = trifluoromethanesulfonic), AgNO3, Ag2SO4, AgBz (Bz = benzoate) and AgSal (Sal = salicylate). The reactions result in the formation of two dinuclear complexes [Ag-2(Ox)(2)(3-dppmapy)(2)] (1, Ox = TFA; 2, Ox = OTF) and four 1D coordination polymers Ag(mu-eta(2)-NO3).3-dppmapy) center dot EtOH (3 center dot EtOH), [Ag-2(mu-eta eta-SO4)(3-dppmapy)(2)] center dot CHCl3 (4 center dot CHCl3), [Ag(mu-eta(2)-Bz)(3-dppmapy)] (5) and [Ag(mu-eta(2)-Sal)(3-dppmapy)] (6). All six compounds have energy bands between 3.11-3.43 eV which is in the range of semiconductive materials, whereas only 6 exhibits good stability in water solution under UV irradiation. In the aqueous phase, 6 exhibits high photocatalytic performance in the degradation of eriochrome black T (EBT), amido black (AB) and nigrosin (NO), and also shows relatively prompt anodic photocurrent responses.
