Trimere Metathioborsäure (HSBS)3

Abstract: Abstract. (HSBS)3, monoclinic, P2x/c, a=13"949 (6), b=4.133 (2), c=17"532 (8) A, fl=114-76 (3) ° , M= 227"84, Z=4, Dexp = 1"63, Dx= 1"649 g cm -3. The molecules form six-membered rings which are nearly planar. The mean values of the cyclic and terminal B-S bond lengths are 1.803 (5)

“…This is in excellent agreement to the bond lengths in the binary compounds and in H 3 B 3 S 6 [36] and B 3 S 3 Br 3 . [38] The three phenyl groups are rotated about the B ± C bonds with different rotational angles.…”

“…[35] E. Wiberg and W. Sturm proposed the structure of H 3 B 3 S 6 to be a cyclic trimeric metathioboric acid, [29] which was proven in 1973 by single crystal X-ray structure determination. [36] The B 3 S 6 entities deviate slightly from a perfectly planar arrangement. The average B ± S distance is 1.803 .…”

“…Another argument for an effective A overlap is the exact planarity (within the limits of error) of the spZ-BS,, BSIR and the BSRz systems (e. g. [38,401) structurally characterized so far. In this context the non-planarity of BZS3(C6H5),, as a further derivative of the trithiadiborolane series, is all the more surprising['"] (Fig.…”

“…Viergliedrige 1,3,2,4-Dithiadiboretane, [24] [29] ein cyclisches Trimer der Metathioborsäure, konnte 1973 durch eine vollständige Einkristall-Röntgenstrukturanalyse bestätigt werden. [36] Im Kristallverband weichen die B 3 S 6 -Einheiten von der exakten Planarität ab; der mittlere B-S-Abstand beträgt 1.803 . Die von Wiberg und Sturm vorgeschlagene Struktur von H 2 B 2 S 4 konnte bislang nicht bestätigt werden, aber J.…”

“…Die B-Q-Bindungslängen zeigen geringe Schwankungen und betragen im Mittel 1.808 (Q S) und 1.93 (Q Se). Diese Werte stimmen hervorragend mit denen der entsprechenden binären Verbindungen und denen von H 3 B 3 S 6 [36] und B 3 S 3 Br 3 [38] überein. Die Phenylgruppen sind gegenüber der Ringebene mit unterschiedlichen Winkeln um die B-C-Bindung gedreht.…”
