Synthese und Charakterisierung von nichtklassischen Polyinterhalogeniden basierend auf Brommonochlorid

Abstract: Aufgrund eines sehr ausgeprägten s-Lochs bildet BrCl stärkere Halogenbrücken als Cl 2 und Br 2 .D iese Stabilisierung ermçglicht die kristallographische Charakterisierung einer Vielzahl neuartiger Polyinterhalogenide mit Chlorid als Zentralion, z. B. in den Kristallstrukturen von [AsPh 4 ][Cl-(BrCl) 3 ]u nd [CCl(NMe 2 ) 2 ][Cl(BrCl) 5 ]. Darüber hinaus wird erstmals die Kristallstruktur eines oktaedrischk oordinierten, nichtklassischen Interhalogenids beschrieben. Das Tridekainterhalogenid-Monoanion [Cl(BrCl) … Show more

“…Thesolid-state structure of the [Cl(BrCl) 6 ] À anion consists of chains that are formed by halogen-halogen interactions (Figure 40). [182] Polyinterhalogen anions of Cl, Br,a nd I: [BrICl] À is the only crystallographic established trihalogen anion with three different halogens.Itwas reported for the first time in 1938 as [NH 4 ][BrICl]. [165] Other examples of this anion have only been obtained in low-dimensional organic conductors of bis(ethylenedithio)tetrathiofulvalene (BEDT-TTF) salts with trihalide counterions and are therefore disordered, or rather ac ombination of different anions.…”

“…[16] These structures are exemplary of the halogen bonding concept [21] as the non-symmetric pseudohalogens ICN, BrCN,a nd ClCN can be compared with interhalogens such as IBr and BrCl. [6,22] Thec alculated electrostatic potential (ESP) shows an even more distinct s-hole at the bromine side of BrCN compared to the BrCl molecule.The maximum ESP (V max )at the center of the s-hole at an electron density of 0.001 au [23] is larger for BrCN (0.068 au) than for BrCl (0.057 au) and bromine (0.048 au).
