Abstract
The reactions between [Mo3(μ3-S)(μ2-S)3(Acac)3(Py)3]PF6 (HAcac is acetylacetone, Py is pyridine) and CuX (X = Cl, I, SCN) afford heterometallic cubane clusters [Mo3(CuX)(μ3-S)4(Acac)3(Py)3]PF6. The structures of two new compounds, [Mo3(CuCl)S4(Acac)3(Py)3]PF6 · 3.25CH2Cl2 · 0.5C6H5CH3 and [Mo3(CuI)S4(Acac)3(Py)3]PF6 · 4C6H6, are determined by X-ray diffraction analysis. All synthesized compounds are characterized by elemental analysis and IR spectra. According to the vibrational spectra, the thiocyanate complex in the solid state is a mixture of the bond isomers [Mo3(CuNCS)S4(Acac)3(Py)3]PF6 and [Mo3(CuSCN)S4(Acac)3(Py)3]PF6, whereas in solution this complex exists as a isothiocyanate form.
