Studies on the triangular cluster [Mo3S13]2−: Electronic structure (Xα calculations, XPS), crystal structure of (Ph4As)2[Mo3S13]. 2CH3CN and a refinement of the crystal structure of (NH4)2[Mo3s13]·H2O

The electronic structure of the triangular thio cluster [Mo3S13]2− has been studied by electronic absorption and XP spectra and is discussed in terms of SCF-Xα-SW calculations. The synthesis and crystal structure of (Ph4As)2[Mo3S13]·2CH3CN, which is soluble in organic solvents, are reported together with a refinement of the crystal structure of (NH4)2[Mo3S13]·H2O.
