| Abstract: | Summary The complex Mo( -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 with-C10H7CS2H. The complex Mo(-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. |
