摘要: Abstract Studies are reported of the electro-optical Kerr effect, electric dipole moments and IR carbonyl stretching frequencies nine EPh 3 (CO) 5 complexes (E P, As or Sb M Cr, Mo W). The experimental results applied in conjunction with molecular mechanics calculations data from X-ray crystal structure analysis, to explore stereostructural preferences M(CO) molecules regard orientations about ME bond phenyl group rotations EC ar . Evidence is drawn together compared for solution solid states as isolated molecules. It found that all states, ring dispositions like helicity favoured coordinated ligands these complexes.
