Abstract Studies are reported of the electro-optical Kerr effect, electric dipole moments and IR carbonyl stretching frequencies of the nine EPh 3 (CO) 5 complexes (E P, As or Sb and M Cr, Mo or W). The experimental results are applied in conjunction with molecular mechanics calculations and data from X-ray crystal structure analysis, to explore the stereostructural preferences of the EPh 3 M(CO) 5 molecules

The bidentate ligands (Ph2Sb)2MMe2 react with Ni(CO)4 to yield the polymericcomplexes [Ph2SbMMe2SbPh2Ni(CO)2]n; 1: M = C, 2: M = Ge; 3: M = Sn. From (THF)Cr(CO)5 and (Ph2Sb)2SnMe2 the dinuclear complex Me2Sn[SbPh2Cr(CO)5]2 4 has been synthesized. Tetramethyldistibane reacts with bicyclo-2,2,1-heptadienetetracarbonylchromium to yield polymeric [(Me2SbSbMe2)Cr(CO)4]n 5.
