Synthesis of Ternary M-C-N Nitrides of Alkaline Earth Metals

The aim of this project is the synthesis and investigation of a novel nitridocarbonates of alkaline earth metals. In particular, we aim to synthesis dimers, oligomers or polymerized networks of the complex anions guanidinate [CN3]5- and ortho-nitridocarbonate [CN4]8-. The justification for high pressure experiments with carbonitrides relies in the recently found SbCN3, which proofs that pressures above ~30 GPa lead to complex C-N anions with higher dimensionality and open a new class of materials potential for optoelectronic applications [1].
