Crowned with success: Stepwise coordination of two kinds of thiolate ligands to a nickel(II) center affords a dodecanuclear ellipse (see structure) and two decanuclear wheel‐like NiII–thiolato clusters. The wavelength‐dependent nonlinear optical behavior of these tiara‐like compounds was investigated and supported by theoretical studies. The results suggest that NiS π bonds play a crucial role.
