Structural investigation of 1,4-diaminobenzene complexes of nickel and cadmium chloride by FT-IR and Raman spectroscopy

Abstract

Infrared and Raman (4000-200 cm(-1)) spectra are reported for 1,4-diaminobenzene complexes of nicker (II) and cadmium (II) chloride, MCl(2)PPD, where M=Ni or Cd and PPD=1,4-diaminobenzene (p-phenylenediamine). Vibrational spectroscopic investigation indicated that complexes have polymeric structures containing bidentate bridging molecules of 1,4-diaminobenzene.
