摘要：

The syntheses and the crystal structures of new multitopic anion-binding organic ligands based on a benzenoid scaffold and bearing two or three 2-iodo-imidazolium arms are reported. The quite short C-I center dot center dot center dot Br- contacts observed in the solid state (0.77 times the normalized contacts) demonstrate the excellent halogen bonding donor ability of iodine atoms in 2-iodoimidazolium cations. The geometric features of obtained bromide anion adducts afford valuable structural insights for the design of effective and selective multitopic anion receptors based on halogen bonding.
