Preparation and optical absorption properties of one‐dimensional organic electron conductors

A series of metal containing organic compounds of the M[HNAFIN]2 · 2TCNQ-type, being M either Ni, Pd, Pt, Cu or Zn, have been prepared and studied in respect to infrared absorption spectra. Characteristic IR absorption spectra for each of the compounds are manifest, depending on the nature of the metal introduced. In particular is the C N stretch mode absorption spectrum for Ni-containing compounds rather sharp and single peaked, while Pt and Zn containing compounds present more complex features.
