A new stable organic metal, TMTTeN(SCN)<SUB>0.88</SUB>, where TMTTeN is 2,3,6,7-tetramethylnaphtho[1,8-<I>cd</I>:4,5-<I>c</I>′<I>d</I>′]bis[1,2] ditellurole, was obtained. The donors are stacked to form columns and three-dimensional network is developed through Te···Te contacts. The salt is highly conductive and keeps metallic behavior down to 4.2 K. Furthermore the salt exhibits Pauli paramagnetic behavior down to 2 K. The extended Hückel tight-binding band calculation was examined.
