Rational synthesis, structural characterization and the third-order nonlinear optical properties of two new M-Cu-S (M = Mo or W) clusters

By the additional reaction of binuclear compounds (Me4N)2M2S4 (TDT)2 (M = Mo, W; H2TDT= H2CH3C6H3S2) with mononuclear cuprous complex, two new M-Cu-S clusters Mo2Cu2S4(TDT)2-(PPh3 )2·CH3CH2OH (1) and W2Cu2S4(TDT)2(PPh3)2·0.5CH3CH2OH-0.5H2O (2) have been prepared and characterized by IR, UV-Vis, 31P NMR spectroscopy, cyclic voltammetry and single crystal X-ray structure analysis . Both compounds crystallize in space group P 21 / n with lattice parameters a = 1.0956(3), b = 2.2072(3), c = 2.4340(3) nm, β= 100.36(2)°, V= 5.790(3) nm3 and Z = 4 for 1 and a = 1.0965(9),b= 2.2135(3), c = 2.4317(4) nm, β = 99.63(8)°, V= 5.819(8) nm3 and Z = 4 for 2. Both molecular structures contain a cubane-like cluster core [M2Cu2S4] (M = Mo, W) and their skeletons are almost the same except for M atoms. The syntheses, structures and spectrum characterizations of these two clusters are discussed. The third-order nonlinear optical (NLO) property of the two clusters was studied by the technique of forward degenerate four
