Contributions to the Chemistry of Silicon-Sulphur Compounds. 53. Structure of 1,3-Dimethyl-1,1,3,3-tetraphenyldisilthiane1,3-Dimethyl-1,1,3,3-tetraphenyldisilthiane was obtained by an insertion reaction of sulphur with Ph2 MeSiH. The compound crystallizes triclinically (P1; a = 1166.7; b = 1231.1; c = 988.6 pm; α = 113.23; β = 90.34; γ = 112.43°; Z = 2). The X-ray structure analysis shows a bent configuration of the molecule with Si—S—Si = 108.7°. The results are discussed together with the structures of hexaphenyldisilthiane and dimethyltetraphenyldisiloxane.
Notes:
1,3-Dimethyl-1,1,3,3-tetraphenyldisilthian entsteht aus Schwefel und Ph2MeSiH in einer Einschub-Reaktion. Die Verbindung kristallisiert triklin (P1; a = 1166,7; b = 1231,1; c = 988,6 pm; α = 113,23; β = 90,34; γ = 112,43°; Z = 2). Die Kristallstruktur-analyse ergab eine gewinkelte Konfiguration des Moleküls mit Si—S—Si = 180,7°. Die Ergebnisse werden im Zusammenhang mit der Struktur des Hexaphenyldisilthians und Dimethyltetraphenyl disiloxans diskutiert.
