1,1′-(Ethane-1,2-di-yl)dipyridinium bis-(iodate)

Abstract

The title salt, C 12H 14N 22+· 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 IO3 - anions with each other along [100], so as to create a three-dimensional network. © Gholizadeh et al. 2011.
