1,1′-(Ethane-1,2-diyl)dipyridinium bis(iodate)

Abstract

The title salt, C12H14N22+·2IO3−, exhibits two crystallographically independent iodate anions, the I atoms of which are each in a trigonal–pyramidal environment. In the dication, the two pyridine rings adopt an anti conformation with respect to each other; the angle between these two rings is 3.84 (19)°. In the crystal structure, C—H...O hydrogen bonds between the cations and anions lead to the formation of layers arranged parallel to the ab plane. I...O halogen bonds [R22(4) graph-set motif] range between 2.873 (2) and 3.036 (3) Å and connect neighbouring IO3− anions with each other along [100], so as to create a three-dimensional network.
