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.
