A ternary tetrathiafulvalenium (TTF{sup +}) salt, based on the trivalent, paramagnetic, hexanuclear, all-inorganic niobium cluster anion Nb{sub 6}Cl{sub 18}{sup 3{minus}}, has been prepared by electrocrystallization and characterized by single-crystal x-ray diffraction and diffuse scattering as well as variable-temperature ESR studies. (TTF{sup +}){sub 2{sup {minus}}}((Nb{sub 6}Cl{sub 18}){sup 3{minus}})((C{sub 2}H{sub 5}){sub 4}N{sup +})(CH{sub 3}CN) is insulating, and the tetragonal (space group P4{sub 2}/ncm) lattice parameters at 140 K are a = 17.929 (6), c = 15.798 (3) {angstrom}, and V = 5,079.0 {angstrom}{sup 3}. The structure presents a rock salt framework with the tetrahedral interstices selectively occupied by tetraethylammonium cations and acetonitrile molecules.
