macrocycles are described, containing either chloro or iodoimidazolium heterocycles. Crystal structure determinations of these macrocycles as their bromide salts are reported, as well as of the nitrate salt of the analogous bis-bromoimidazolium macrocycle. In all structures, short halogen bonds are observed in the solidstate, with the nitrate complex of the bis-bromoimidazolium macrocycle containing a particularly
