Structure and Thermal Properties of Lithium Cyanate

Abstract

The synthesis, structural, and thermal characterization of lithium cyanate are reported in this work. LiOCN forms crystals in the trigonal crystal system. The structure was solved in the space group R3m. It is isomorphous to the structure of sodium cyanate. In the tem-

Development of Metal Cyanurates: The Example of Barium Cyanurate (BCY)

“…Previously, the employment of Li(OCN) and SrCl 2 (and SrF 2 ) have yielded LiSr(O 3 C 3 N 3 ) and Li 3 Sr 2 F(O 3 C 3 N 3 ) 2 . From these reactions it became clear to us that the employment of Li(OCN) is limited, because it shows decomposition effects above 475 °C with the formation of carbonate as a decomposition product 12. Therefore, we decided to explore the usage of K(OCN).…”

The Quasi‐Binary Acetonitriletriide Sr3[C2N]2

“…The discovery that these anions could be stabilised in a solid‐state system lead to the question whether quasi‐binary acetonitriletriide compounds could be produced, since the similar anion [CN 2 ] 2− produces a large range of quasi‐binary compounds, for example, M 2 [CN 2 ] ( M =Li–Cs) and M [CN 2 ] ( M =Be–Ba, Mn–Zn, Cd, Pb, and Eu) . In addition, other linear three‐atom ions, such as [N 3 ] − , [C 3 ] 4− , [BN 2 ] 3− , [OCN] − , and [CBN] 4− , have also produced quasi‐binary and higher compounds . Herein, we report the first quasi‐binary acetonitriletriide, which was characterised by single‐crystal X‐ray diffraction, Raman spectroscopy, and elemental analysis, as well as quantum‐chemical methods.…”

Das quasi‐binäre Acetonitriltriid Sr3[C2N]2

“…Dieses Anion wurde bisher nur selten beobachtet, Beispiele in Festkörpern wurden mit Ba 5 [TaN 4 ][C 2 N] und Sr 4 N[CN 2 ][C 2 N] berichtet . Da eine Vielfalt an quasi‐binären Verbindungen mit dem sehr ähnlichen [CN 2 ] 2− ‐Ion bekannt ist, zum Beispiel M 2 [CN 2 ] ( M =Li–Cs) oder M [CN 2 ] ( M =Be–Ba, Mn–Zn, Cd, Pb und Eu), und weitere lineare dreiatomige Ionen wie [N 3 ] − , [C 3 ] 4− , [BN 2 ] 3− , [OCN] − und [CBN] 4− (quasi‐)binäre und höhere Verbindungen hervorgebracht haben, suchten wir nach analogen quasi‐binären Acetonitriltriiden. Hier berichten wir nun über Sr 3 [C 2 N] 2 , das erste quasi‐binäre Acetonitriltriid, das wir mittels Einkristall‐Röntgenbeugung, Raman‐Spektroskopie und Elementaranalyse sowie quantenchemischen Methoden charakterisiert haben.…”
