Abstract: 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-pressurehigh-temperature (HPHT) synthesis of Bi$_7$C$_{ 10}$N$_{18}$(N$_{3(1‐ x )}$O$_{3x}$ ), which features double-layers of poly-N-(1,3,5-triazin-2-yl)-guanidine [C4 N6x- ]n and non-polymerized guanidinate anions CN 35- . The structure model was determined by means ofsynchrotron 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─N network and represents the first intermediatebetween highly charged CN 35− 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 intoan alternative synthesis route to classical polycondensation reactions
