| Abstract: | Tetracarbonyl Chromium Complexes with Me2SbESbMe2 (E = O, S) and MeSb(SSbMe2)2 as Ligands Me2SbOSbMe2 reacts with nbdCr(CO)4 (nbd = norbornadiene) to form cyclo-Me2SbOSbMe2Cr(CO)4]2 ( 1 ). The reaction of Me2SbSSbMe2 with nbdCr(CO)4 gives cis-(Me2SbSSbMe2)2Cr(CO)4] ( 2 ), a complex stable only in solution. With excess nbdCr(CO)4 also cycloMe2SbSSbMe2Cr(CO)4]2 ( 3 ) and cycloMeSb(SSbMe2)2Cr(CO)4] ( 4 ) form in low yield. The crystal structures of 1 , 3 and 4 · nbdCr(CO)4 are reported. The novel ligand MeSb(SSbMe2)2 is formed by elimination of Me3Sb from Me2SbSSbMe2. |
