Dianionic and neutral bis TTF dithiolate mercury and nickel complexes have been prepared. X-ray structural studies show the geometry around the mercury to be tetrahedral and CV and esr measurements indicate very little interaction between the two TTF based ligands. Conductivity measurements on the neutral mercury complexes gave sigma(RT) = 10(-5) Scm(-1) whereas for the neutral nickel complexes values of 10(-2) - 10(-1) Scm(-1) are observed. The salts [TTF](x)[Fe(tdas)(2)] x = 2, 3/2 (tdas = 1,2,5-thiadiazole-3,4-dithiol) have been prepared by electrocrystallisation and show conductivities of 10(-2) Scm(-1) and 10(-5) Scm(-1) respectively. The former salt displays thermally activated magnetic behaviour and the latter shows a Curie-type temperature dependance.
