Tetranuclear [Cu<sub>4</sub>(μ<sub>2</sub>-dppm)<sub>3</sub>(μ<sub>2</sub>-μ<sub>2</sub>-NS<sub>2</sub>)(μ<sub>2</sub>-μ<sub>4</sub>-NS<sub>2</sub>)] (<b>1</b>) and pentanuclear [Cu<sub>5</sub>(μ<sub>2</sub>-dppm)<sub>4</sub>(μ<sub>3</sub>-μ-<sub>3</sub>-NS<sub>2</sub>)<sub>2</sub>]PF<sub>6</sub> (<b>2</b>·PF<sub>6</sub>) (dppm = bis(diphenylphoshino)methane, NS<sub>2</sub><sup>2-</sup> = 1,8-naphthalenedithiolate)
were synthesized from the reactions between NS<sub>2</sub><sup>2-</sup> and [Cu<sub>2</sub>(μ<sub>2</sub>-dppm)<sub>2</sub>(CH<sub>3</sub>CN)<sub>2</sub>](PF<sub>6</sub>)<sub>2</sub>. Compound <b>1</b> features a square Cu<sub>4</sub> core
capped by a 5-coordinate S atom while <b>2</b>·PF<sub>6</sub> exhibits an
unprecedented square planar Cu<sub>5</sub> core. Both complexes display
dual emissions at 480 and 620 nm which arise from ligand-centered
nπ* and ligand−metal charge-transfer excited states, respectively.
