Complexes of aromatic diamines with copper (II) salts have been prepared and cha­racterized by infra-red, electronic spectral analysis and magnetic measurements. The complexes are of the type CuLX2; where L=o-phenylenediamine and X=Cl: or Bi, having a polymeric octahedral structure; and CuL~2; where L=o-phenylenediamine, 1,8-diaminonapthalene or 2,2-diamin0bi­phenyl, and x=cr, Bi, NOj CL04 and 804 which are shown to be of a distorted octahedral nature.
