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

The title salt, C(12)H(14)N(2) (2+)·2IO(3) (−), 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 [R (2) (2)(4) graph-set motif] range between 2.873 (2) and 3.036 (3) Å and connect neighbouring IO(3) (−) anions with each other along [100], so as to create a three-dimensional network.
