Built-in TTF–TCNQ charge-transfer salts in π-stacked pillared layer frameworks

A TTF–TCNQ charge-transfer salt was incorporated in a layer structure with paddlewheel-type carboxylate-bridged dirhodium(II, II) complexes ([Rh2]) to construct π-stacked pillared layer frameworks of formula (TTF)n[{Rh}2(TCNQ)] (n = 1 or 2).
