Synthesis and structural characterization of the novel cluster compound {[Mo3S7(dtp)(3)](4)center dot I}{(HgI3)(3)}center dot 4 H2O (dtp = S2P(OC2H5)(2)(-))

Reaction of [Mo3Y(mu -S)(3)(dtp)(4)(H2O)] (Y = O. S: dtp=S2P(OC2H5)(2)) wit h HgI2 gave the novel compound ([Mo3S7(dtp)(3)](4).I}{(HgI3)(3)}. 4H(2)O (1 ). which contains a {[MO3S7(dtp)(3)](4).I} tetramer and (HgI3)(-). Compound 1 has been characterized by IR, Raman. UV/Vis. and NMR spectroscopy and si ngle-crystal X-ray diffraction analysis. It is shown that this formation pr ocess can be referred to as a new cluster reaction. The structure and spect roscopic data of the tetramer is also compared with that of the related dis crete cluster [Mo3S7(dtp)(3).I]. Crystal data: space group F23, a = 26.756( 3) Angstrom, V= 19218.7(4) Angstrom (3), Z = 4, R = 0.059.
