Cover illustration: A packing diagram for 3-bromopyridinium tribromoacetate, illustrating the layer structure formed via classical hydrogen bonds, C-HO interactions and BrBr contacts (all shown as dashed lines), viewed perpendicular to (102). H atoms not involved in hydrogen bonds have been omitted for clarity. See Jones & Lozano [Acta Cryst. (2004), C60, o876-o878].
