| Abstract: | A method for the preparation of (C6H5)nPX3-nCr(CO)5 complexes in the crystalline state is described. The carbon-oxygen stretching vibration, vCO(A, eq.), of the complexes with X = Cl, Br, I is mainly determined by the inductive effect of the (C6H5)nPX3-n group. For X = H, the vCO band is defined by the concomitant influence of the σ, π and steric effects. |
