| Description: |
Application of high-pressure conditions in chemical synthesis has proven to access a wide range of novel nitrogen-rich compounds and to overcome the stability of the dinitrogen molecule. In the present work, we report the high-pressure high-temperature (HPHT) synthesis of Bi7C10N18(N3(1-x)O3x), which features double-layers of poly-N-(1,3,5-triazin-2-yl)-guanidine [C4N6x-]n and non-polymerized guanidinate anions CN35-. The structure model was determined by means of synchrotron single-crystal X-ray diffraction and is fully corroborated by theoretical calculations. The poly-N-(1,3,5-triazin-2-yl)-guanidine illustrates an example of a 2D polymerized anionic C & horbar;N network and represents the first intermediate between highly charged CN35- anions and fully condensed graphitic carbon nitride networks achieved by HPHT conditions. This opens a pathway to a widely varied family of hydrogen-free nitridocarbonates, which has the potential to develop into an alternative synthesis route to classical polycondensation reactions. ; Funding Agencies|Deutsche Forschungsgemeinschaft (DFG) [BY112/2-1, BY101/2-1]; European Union (ERC) [101077963]; Johanna-Quandt Young Academy; Loewe Start Professorship Program of the state of Hesse; Adolph-Christ foundation; Knut and Alice Wallenberg Foundation [KAW-2018.0194]; Swedish Research Council (VR) [2023-05358]; Swedish Government Strategic Research Areas in Materials Science on Functional Materials at Linkoping University [2009 00971]; Swedish Research Council [2022-06725]; Projekt DEAL; Swedish Research Council [2023-05358] Funding Source: Swedish Research Council |
