Abstract
Oxidation of tetrathiafulvalene with CuCl2.2H2O in ethanol produced the mixed valence metallotetrathia-ethylene (TTF) 3(CuCl2)5 containing both TTF +· and TTF2+, which was converted into (TTF) 2 CuCl4 on dissolution in hot acetonitrile while the CuCl42- and BF4- salts of TTF 2+ were prepared using CuCl2·2H2O and Cu(BF4)2 in acetonitrile; resonance Raman spectroscopy was used to probe the oxidation state of TTF in these copper metallotetrathiafulvalenes, and e.s.r. and magnetic susceptibility data indicate the presence of three-dimensional magnetic interactions in the TTF+ and TTF2+ CuCl42- salts.

From the equation relating linewidths, exchange fields, and dipolar fields,g a value for the exchange field based on three dimen- sional interactions was calculated to be ca. lo4GI in reason- able agreement with the experimental 8 values. [Dipolar fields were assumed to be several hundred gauss in both (3) and (Q)].
