Abstract: | In the title compound, (C10H9NOS6)K[Hg(SCN)4] or (EDT–TTF–CONHMe)K[Hg(SCN)4)], fully oxidized organic (EDT–TTF–CONHMe)+· radical cations form quasi‐one‐dimensional stacks running along the monoclinic 21 axis and alternating along the crystallographic [101] direction with inorganic anion stacks made from mixed K+–[Hg(SCN)4]2− ribbons. For each anion, three essentially collinear SCN ligands interact with the K+ ions via short N⋯K contacts, while the terminal N atom of the fourth SCN group is engaged in a number of hydrogen‐bond contacts with the –CH, –NH and –CH2 hydrogen‐bond donors of the amide function. Radical cations are dimerized along the stacks and the crystal conductivity is activated. |
