New amide functional tetrathiafulvalene ligands containing naphthyridine moiety (rong class="boldFont">Lrong>rong class="boldFont">1rong>rong class="boldFont">-Lrong>rong class="boldFont">3rong>) were synthesized. Further coordination reactions of these ligands with Re(CO)5Cl afford three interesting rhenium tricarbonyl complexes, ClRe(CO)3(L). Crystal structures of ClRe(CO)3(rong class="boldFont">Lrong>rong class="boldFont">1rong>) (rong class="boldFont">1rong>) and ClRe(CO)3(rong class="boldFont">Lrong>rong class="boldFont">2rong>) (rong class="boldFont">2rong>) have been determined. Electrochemical and spectroscopic properties of all compounds are investigated.
