Abstract

A large number of [Formula: see text] and Co2 (CO) 4 (LL)-substituted alkyne complexes (LL= dppa and dmpm) have been prepared, characterized and studied by cyclic and square- wave voltammetry. In this paper we report a comparative electrochemical study of 2, 5-, 2, 4-, 3, 4-and 2, 3-bis (trimethylsilylethynyl) thiophene dicobalt substituted alkyne complexes, in order to evaluate the extent of the electronic interaction between the “Co2C2” redox ...
