spectral data of 38 complexes of the type cis - and trans -W(CO) 4 (PR 3 )(L) are presented. The much larger chemical shift range for a particular phosphine in cis compounds is shown to arise mainly from steric interactions. 1 J(W–P) depends on the electronegativity of the substituents at phosphorus and the nature of the trans ligand. A trans influence series for octahedral tungsten(O) is derived: SbPh
