A new type of conductive coordination compound of C-n[M(dmit)(2)] (M =
Ni, Pd, Pt, n = 2, 1) has been obtained by introducing unsaturated he
terocyclic cations (N - methylpyridine cation, N - methylquinoline cat
ion and N - methylbenzothiazole cation) and trimethylphenyl ammonium i
nto the system of [Ni(dmit)(2)](n-). The components and structures of
these new compounds have been determined, IR spectra, ESR spectra, XPS
spectra, UV spectra, magnetic susceptibilities and conductivities wer
e studied. It is concluded that the charge number and distribution of
the anion can be influenced by the outer cations, therefore, the elect
rical property of the complexes was influenced by the cations through
another way.
