摘要：
Both the homometal cluster [P(ph(4))](2)[Mo2O2(mu-S)(2)(S-2)(2)] (1) and [Mo2O2(mu-S)(2)(Et(2)dtc)(2)] (2) (Et(2)dtc = diethyl-dithiocarbamate) were successfully synthesized by low-temperature solid-state reactions. X-ray single-crystal diffraction studies suggest that compound (1) is a dinuclear anion cluster, and compound (2) is a dinuclear neutral cluster. The two compounds were characterized by elemental analyses, IR spectra and UV-Vis spectra. The third-order non-linear optical (NLO) properties of the clusters were also investigated and all exhibited nice non-linear absorption and self-defocusing performance with moduli of the hyperpolarizabilities 5.145 x 10(-30) esu for (1) and 5.428 x 10(-30) esu for (2).
