TLDR
In this article, the structure of 1h was determined by means of an X-ray analysis, which was considered in connection with the increase of electron density and compared with the results of the Xray analysis of CH3Si(NSN)3SiCH3 (2).Abstract:
Die Umsetzung von S4N4O2 mit Nucleophilen (Alkoholate, Alkohole, Azide und Isocyanate) in alkoholischem Medium fuhrt zu den Salzen 1a–h. Fur 1h wurde eine Rontgenstrukturanalyse durchgefuhrt. 1h kristallisiert in der Raumgruppe P21/n und enthalt eine transannulare SS Bindung mit 248.2 (2) pm. Die Struktur von 1h wird im Zusammenhang mit der Zunahme der Elektronendichte betrachtet und mit den Ergebnissen der Rontgenstrukturanalyse von CH3Si(NSN)3SiCH3 (2) verglichen. 2 kristallisiert kubisch (Raumgruppe P4132). Das bicyclische Molekul (SN 150.4 (2), SiN 173.7 (2)pm) hat praktisch D3h Symmetrie und zeigt keine SS-Bindungen im Ring.
Salts of S4N4O2 – Examples for the Dependence of the Structure of Cyclic Sulfur-Nitrogen Compounds on the Electron Density
The reaction of S4N4O2 with nucleophiles (alcoholates, alcohols, azides, and isocyanates) in alcoholic solution leads to the salts 1a–h. The Structure of 1h was determined by means of an X-ray analysis. 1h crystallizes in the space group P21/n and contains a transannular SS-bond with 248.2 (2) pm. The structure of 1h is considered in connection with the increase of electron density and compared with the results of the X-ray analysis of CH3Si(NSN)3SiCH3 (2). 2 is cubic (space group P4132). The bicyclic molecule (SN 150.4(2), SiN 173.7 (2) pm) has approximate D3h symmetry and shows no SS bonds across the rings.read more
