On the reported pyridinium pentachlorothallate(III) and some related compounds

Inorganica Chimica Acta, 1984
Abstract While (C 5 H 6 N) 2 TlCl 5 cannot be prepared in water via the reported procedure it may be obtained in non-aqueous media. Although its low-energy infrared spectrum contains broad peaks and the Raman spectrum is deceptively simple, comparison of these spectra with those of other TlCl 4 − , TlCl 5 3− and TlCl 6 3− derivatives shows that

Secondary interactions in the isomorphous compounds 2,6-bis(chloromethyl)pyridinium chloride and 2,6-bis(bromomethyl)pyridinium bromide

Acta Crystallographica Section C Crystal Structure Communications, 2004
The title compounds, C7H8Cl2N+.Cl- and C7H8Br2N+.Br-, are isomorphous. In the crystal packing, layers parallel to the ac plane are formed by a classical N(+)-H...X- hydrogen bond (X = halogen) and two X...X contacts. A third X...X contact links the layers, and a fourth, which is however very long, completes a ladder-like motif of halogen atoms ...
