Abstract

The reaction of the Hofmann-type inclusion compounds (CP4H5N)Ni(CN)2NH3 (I) and (C6H5NH2)Ni(CN)2NH3 (II) with various oxidants is reported to yield electrically conductive polypyrrole/Ni(CN)2NH3 (III) and polyaniline/Ni(CN)2NH3 (IV) type composites. (III) is a conductive material while (IV) is an insulator. The synthetic details as well as spectroscopic electron microscopic and X-ray diffraction data on the state of the polymers inside the Ni(CN)2NH3 host material are presented. Data obtained from single crystals of these materials are presented, as well as variable temperature charge transport measurements such as electrical conductivity and thermopower.
