Infrared spectra of adducts of tetrasulfur tetranitride with metal halides

Abstract: New complexes of S4N4 with TiBr4, ZrCl4, NbCl5, and TaCl5 have been prepared. The infrared spectra of these complexes together with the spectra of previously reported complexes have been determined. Possible structures for the complexes are discussed.

“…The formation of TiCl 4 adducts with Lewis-bases was observed before, and especially the cage-like S 4 N 4 molecule showed a variety of possibilities to connect with the metal chloride. For example, [(TiCl 4 )(S 4 N 4 )] 2 molecules have been observed and structurally characterized earlier [3,4]. Organophosphanes can also act as electron donors towards titanium, e.g., in [(TiCl 4 )(Ph 3 P)] or [(TiCl 4 )(Ph 3 PCh)] (Ch = O, S) [5,6].…”

“…After 16 h the sublimation was stopped, whereupon the i.r. spectrum of the residue showed weakening of the bands due to compound (2), whereas those at 844 and 465 cm-' became stronger. After further heating of the sample at 110 "C in uacuo (6 h) only traces of (2) continued to sublime out.…”

“…Alange und Banister führen in einer Zusammenstellung aus dem Jahr 1978 etwa 50 solche Verbindungen auf [3]. Die Struktur der meisten Verbindungen ist unbekannt; häufig steht nicht einmal fest, ob die Produkte tatsächlich intakte S 4 N 4 -Neutralliganden enthalten oder ob das Chamäleon S 4 N 4 unter den speziellen Reaktionsbedingungen weiterreagiert hat, etwa unter Bildung von S 2 N 2 -Komplexen oder unter Ablauf von Redoxreaktionen [4], Wölbling beschrieb 1908 die Darstellung von braunem "N 4 S 4 -TiCl 4 " [1]-Ashley und Torrible schlössen aus IR-Daten, daß S 4 N 4 in diesem Produkt als einzähniger Ligand vorliegt und daß der Komplex zweikernig ist [5], Roesky et al isolierten kürzlich eine gelbe Form von "S 4 N 4 • TiCl 4 ", für die sie eine cisKoordination eines zweizähnigen S 4 N 4 -Liganden aufgrund von IR-Beobachtungen vorschlugen [6]. Eine Struktur mit l,5-N,N'-gebundenem S 4 N 4 war schon früher für "TiCl 4 -S 4 N 4 " vorgeschlagen worden [7].…”
