description The search for new heterometallic metal pseudohalides will be significant for the development of novel functional materials. In this work, a new silver/cadmium heterometallic thiocyanate templated by benzyl viologen has been synthesized and structurally determined, i.e., {(BV)[Ag<sub>2</sub>Cd(SCN)<sub>6</sub>]}<i><sub>n</sub></i> (BV<sup>2+</sup> = benzyl viologen). The interesting 1-D double chain [Ag<sub>2</sub>Cd(SCN)<sub>6</sub>]<i><sub>n</sub></i><sup>2<i>n</i>−</sup> was constructed from the CdN<sub>6</sub> octahedron and Ag<sub>2</sub>SCN<sub>6</sub> dimers via μ<sub>2</sub>-SCN and μ<sub>3</sub>-S,S N SCN bridge, in which the Ag···Ag interaction can be found. Inter-molecular C-H···S/N hydrogen bonds between BV<sup>2+</sup> cations and [Ag<sub>2</sub>Cd(SCN)<sub>6</sub>]<i><sub>n</sub></i><sup>2<i>n</i>−</sup> chains contribute to the formation of a stable 3-D network. The short S···N distance implies the strong charge transfer (CT) interactions between the electron-rich silver/cadmium thiocyanate donor and BV<sup>2+</sup> acceptor. This hybrid can exhibit a photo-generated current performance with an intensity of 1.75 × 10<sup>−8</sup> A. Interestingly, this hybrid can present good photocatalytic degradation performance on rhodamine B in artificial seawater with a degradation ratio of 86.5% in 240 min. This work provides a new catalyst way for the organic dye-type ocean pollutant treatments.
