Abstract : A series of monometallic and bimetallic transition metal complexes have been synthesized for incorporation into highly conductive and potentially superconductive materials. Studies of Ni(dmit)2(C(+))(x), as a function of cation (C(+)) type, have allowed elucidation of the effect of structure on electronic properties. A new class of bimetallic tetrathiooxalate (tto) bridged compounds were discovered that form new synthetic conductors. For example, the reaction of (Bu4N)2?ttoNi(dmit)2! with (TTF)3(BF4)2 led to a material with a conductivity of 0.4 S/cm. A full study of seven new bimetallic, and one new tetrametallic, complex has been carried out with single crystal X-ray structures determined.
