of isomers. The major isomer ( 7 , X=Cl; 8a , X=Br; 9a , X=I) has cis P atoms, trans CO groups and the halide located trans to the phosphorus atom of the ortho -metallated phosphite ligand. The structure of 9a was confirmed by an X-ray diffraction study. Two other isomers, designated 8b (X=Br) and 9b (X=I), with cis P atoms and cis CO groups were isolated from the reactions of [ 2 ] − with Br 2 and
