Oxalato based organic conductors were prepared with M(ox)(2), M(ox)(3) (M=A
l, Cr, Cu, Pt, Fe) using BEDT-TTF, BEDO-TTF, TMTSF, and their crystallograp
hic, electronic, and magnetic properties were investigated. Partial charge
transferred compounds were obtained aside from the materials with the integ
er charge state of donor molecules. Complexes of bimetal-oxalato system MM'
(ox)(3) (M, M-1=Mn, Cr) was also prepared and the coexistence of high condu
ctivity and ferromagnetic correlation was observed.
