title: 3-Methylamido-3',4'-ethylenedithiotetrathiafulvalene(+) potassium tetraisothiocyanatomercury(II).
abstract: In the title compound, (C(10)H(9)NOS(6))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 2(1) 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 -CH(2) hydrogen-bond donors of the amide function. Radical cations are dimerized along the stacks and the crystal conductivity is activated.
