Notes: Summary The complex [PhCH2PPh3]2[Mo2O2S2(SC2H4S)2] has been prepared by reaction of [PhCH2PPh3][MoO(SC2H4S)2] with phenylhydrazine and characterized by single-crystal x-ray structure analysis. This revealed that each molybdenum displays square pyramidal geometry with the terminal oxo-groups in the apical position and the sulphur donors of the dimer-captoethane ligand and the bridging sulphido-ligands generating the basal plane. The related complex [HNEt3]2-[Mo2S4(SC2H4S)2], synthesised by reaction of the MoVI butandiolato-complex [MoO2(butanediolato)2]: 2(butanediol) with triethylamine and ethanedithiol, has also been characterised crystallographically. The structure displays the previously characterized [Mo2S4]2+ core. The anion geometry is analogous to that observed for the oxo-derivative [Mo2O2S2(SC3H4S)2]−2 with the apical oxo-ligand replaced by a sulphido-group.

Notes: Summary The complex Mo(α-C10H7CS2)4 has been prepared from several starting materials: [Mo(NNHPh)2(butane-2,3-diolate)2] · H2NNHPh, [MoCl(NNMe2)2(PPh3)2]+Cl−, [MoO2 (MeCHOCHOHMe)2] · 2MeCHOHCHOHMe or [(C4H9)4N]6Mo7O24, reacted withα-C10H7CS2H. The complex Mo(α-C10H7CS2)4 crystallizes from CH2Cl2-Et2O in the orthorhombic space group Pbca,a=13.655(3)Å,b=21.707(5)Å,c= 26.365(2)Å, V=7814.81Å3, Z=8; 5075 reflections collected, 2723 used in solution to give R=0.0517, Rw=0.0564. The molybdenum is eight coordinate with geometry approximating to aD 2d dodecahedron. The average Mo-S bond lengths are 2.526(3)Å and 2.479(3)Å for the dodecahedrala andb sites, respectively.
