Dodecanuclear-Ellipse and Decanuclear-Wheel Nickel(II) Thiolato Clusters with Efficient Femtosecond Nonlinear Absorption

Abstract

(Figure Presented) 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 Ni-S π bonds play a crucial role.
