Über das Dimethyl(n-propyl)phenylammoniumtriiodid n-PrMe2PhNI3 und die Reihe der Dimethyl(isopropyl)phenylammoniumpolyiodide i-PrMe2PhNIx mit x = 3, 5, 7, 8, 9

Abstract: Die bisher nicht beschriebenen Verbindungen n‐PrMe2PhNI3 und i‐PrMe2PhNIx mit x = 3, 5, 7, 8, 9 wurden durch Umsetzung von Iod mit n‐PrMe2PhNI in ethanolischer Lösung oder mit i‐PrMe2PhNI in methanolischer Lösung dargestellt und ihre Kristallstrukturen durch Röntgenbeugung an Einkristallen ermittelt. Das Triiodid n‐PrMe2PhNI3 besitzt eine Schichtstruktur, in der die anionischen und kationischen Schichten im Wechsel gestapelt sind. Auch die ähnliche, aber nicht isotype Struktur des Triiodids i‐PrMe2PhNI3 läßt s… Show more

“…The trigonal pyramidal heptaiodide with an additional iodine molecule was found for [NMe 4 ][I 9 ] . Note, all these crystal structures show different kinds of networks . Consequently, the coordination number around the central halogenide can decrease from bromine to iodine that could be possibly explained by the better electron‐acceptor properties of iodine with its positive electrostatic potential, the σ‐hole along the X–X axis.…”

“…A small number of nona‐iodides has been structurally established, of which only the structures A and B in Figure 4 come close to a [I(I 2 ) 4 ] − configuration 12. The remaining three should rather be formulated as [(I 3 )(I 2 ) 3 ] − (C, D) and [(I 5 )(I 2 ) 2 ] − (E), respectively 1315. In A and B the mean I − –I distances are, at 323 and 338 pm, much shorter than the sum of the ionic radius of iodide and the covalent radius of iodine, 353 pm.…”

“…For structures of 4-nitroanilinine-monohalide salts, see: Lemmerer & Billing (2006) (bromine) and Ploug-Sørensen & Andersen (1982) (chlorine). For other amine-based triiodide salts, see: Tebbe & Loukili (1998). For a triiodide salt containing a tetraphenylphosphonium cation, see: Parvez et al (1996).…”

“…Polyiodide salts are commonly found, but the triiodides less so. Tebbe & Loukili (1998) have successfully synthesized two tertiary ammonium triiodide salts, while Parvez et al (1996) synthesized a tetraphenylphosphonium triiodide salt. This is important to note since the title compound has a primary amine as the cation, while in the other three reported cases, bulky counter cations are involved.…”
