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

The title salt, C12H14N2 2+·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 [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

Investigation of the Reaction of Dithiocarbamic Acid Salts with Aromatic Aldehydes

A reaction of dithiocarbamic acid salts with carbonyl compounds was investigated for the first time in the presence of BF₃·OEt₂. The reaction is temperature dependent and gives <i>gem</i>-bis(dithiocarbamates) at 35–45 °C as a molecule with high equivalents of dithiocarbamate groups. At lower temperatures (15–20 °C), the 2-iminium-1,3-dithietane is obtained as the only product. The structure of a 2-iminium-1,3-dithietane was accomplished by X-ray crystallographic analysis
