“…During the last decade, there has been considerable interest in the structure and properties of species obtained by combining protonated aromatic nitrogen bases with halide or polyhalide ions (E1- Kholi et al, 1988;Hendrixson et aI., 1991;Liu et al, 1991Liu et al, , 1992. Among these aromatic nitrogen bases, 1,10phcnanthroline is a good candidate for study as it has two close aromatic N atoms which can be neutral, mono-…”

“…Its Raman spectrum is dominated by a very intense band at 164.2 cm –1 (Figure ). A crystal structure with the same composition, but with a different polymeric network of the anions has already been reported . Recrystallization of the less soluble main precipitate from H 2 O/HI gave large amounts of [pyridineH + ] 2 [I 4 ] 2– .…”

“…Ausgehend von freien, V-fo È rmigen Pentaiodid-Einheiten I 5 ± la È ût sich die Ver- Anion I 13 3± beobachtet, in dem aber das Iodid-Ion I ± statt durch ein weiteres Iodmoleku È l mit zwei zusa È tzlichen V-fo È rmigen Pentaiodid-Einheiten u È ber einen langen Abstand (360,63 pm) koordiniert ist [21]. Ein linearer zick-zack-fo È rmiger Verband mit erga È nzenden Iodmoleku È len in trans-Anordnung wurde auch bei vernetzten V-fo È rmigen Pentaiodid-Ionen im (b-Napht)I 5 [22], (pyH)I 5 [23] und [(2-MePh) 3 (Me 3 P) 2 Re]I 5 [24] und bei einem Y-fo È rmigen Pentaiodid-Ion im (BipyH)I 5 [25] beobachtet. Ein Beispiel fu È r ein Pentaiodid mit gleicher Raumsymmetrie (P2 1 /c) und einem a È hnlichen Tetraorganylammonium-Kation ist die Verbindung EtMe 2 PhNI 5 , bei der zick-zack-fo È rmige Ketten u È ber einen kurzen Kontakt vernetzt sind und einen fast planaren zehngliedrigen Ring und einen sesselfo È rmigen vierzehngliedrigen Ring bilden [5].…”
