✦ Synopsis

The homometal cluster [Fe(DMF) 6 ][W 2 (l 2 -S) 2 S 4 ] 1 (DMF = dimethylformamide) was successfully synthesized by low-temperature solid-state reactions. X-ray single-crystal diffraction studies reveal that compound 1 is dinuclear anion cluster. The compound was characterized by elemental analyses, IR spectra and UV-vis spectra. The third-order non-linear optical (NLO) properties of the cluster were also investigated and exhibited non-linear rare saturation absorption (a 2 < 0) and self-defocusing performance with modulus of the hyperpolarizabilities 9.547 • 10 À31 esu for 1.
