摘要：

The title furanoquinonoid compounds have been prepared in order to design new oxygen-containing organic metals, but most of them behaved as weak electron acceptors to form low-conductive molecular complexes. An X-ray crystallographic analysis of the TTF complex of 5,5'-bis(dicyanomethylene)-5,5'-dihydro-DELTA-2,2'-bifuran revealed that the bifuranoquinonoid conjugation takes a planar trans form and the embedded oxygens do not take part in any intermolecular interaction. On the other hand, 3,3'-dibromo-5,5'-bis(dicyanomethylene)-5,5'-dihydro-DELTA-2,2'-bifuran as a modified acceptor gave a high-conductive TTT complex of 2.4 Scm-1.
