SYNTHESIS AND INFRARED STUDY OF (C6H5)nPX3-nCr(CO)5 (X=Cl, Br, I, H; n=0-3) AND (C6H5)2PRCr(CO)5 (R=METHYL, ETHYL, i-PROPYL, t-BUTYL) COMPOUNDS

A method for the preparation of (C6H5)nPX3-nCr(CO)5 complexes in the crystalline state is described.The carbon-oxygen stretching vibration, νCO(A1 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 νCO band is defined by the concomitant influence of the ?, ? and steric effects.
