abstract One novel three-dimensional (3-D) copper(I)-thioarsenate(III) [Ni(en)(3)]Cu4As4S9 (1, en = ethylenediamine) has been solvothermally prepared with the utilization of the in situ formation of [Ni(en)(3)](2+) complex as structure-directing agent (SDA). 1 contains cubane-like [Cu8S12](16-) clusters and rare tetrameric [As4S9](6-) units, which are interconnected to generate the first example of a 3-D anionic framework [Cu4As4S9](n)(2n-), topologically identical to pyrite, and having large channels filled by [Ni(en)(3)](2+) complex cations. 1 is a potential wide-band-gap semiconductor with an energy gap of 1.91 eV that exhibits selectively photocatalytic degradation of methylene blue under visible-light irradiation. The density functional theory calculation, photocurrent response, and magnetic properties of 1 were also investigated.
