Ethidium hepta-fluoro-butyrate.

ABSTRACT: In the title compound (systematic name: 3,8-diamino-5-ethyl-6-phenylphenanthridin-5-ium 2,2,3,3,4,4,4-heptafluorobutyrate), C₂₁H₂₀N₃ ⁺·C₄F₇O₂ ^-, two ethidium ions, C₂₁H₂₀N₃ ⁺ form a dimerized structure due to π-π inter-actions, even though they are positively charged. The hepta-fluoro-butyrate anions are connected to neighbouring cation dimers via hydrogen-bonding inter-actions, the hydrogen-bonding donor sites of the -NH₂ groups of the ethidium ions connecting to the hydrogen-bonding acceptor sites of the -COO^- groups of the hepta-fluoro-butyrate anions.
