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.
