چکیده انگلیسی
Recent advances in the chemistry of two peculiar nitrogen-based materials, that is, ternary itinerant iron nitrides and unsubstituted guanidinate salts, are reviewed. Key to their synthesis is the versatile tool ammonia, either as a gas or as a liquid. For metallic nitrides MxFe4âxN including transition-metal and main-group elements M, it is of paramount importance to follow an improved ammonolytic reaction for achieving both stable and metastable compounds; in addition, there is a magnetic effect acting on the crystal structure of GaxFe4âxN, and one also finds spin-glass behavior in main-group nitrides (MÂ =Â Ga, Ge, Sn). The guanidinate review features an oxidation-controlled low-temperature synthesis of Yb salts, the first magnetic guanidinates, and the doubly-deprotonated guanidinates; the latter represent the all-nitrogen analogues of the ubiquitous carbonates. The covered guanidinates adopt the compositions MCN3H4, M(CN3H4)2, M(CN3H4)3 and MC(NH)3 (MÂ =Â Li-Cs, Sr, Eu, Yb). We also cover the application of first-principles calculations at all levels to gain a deeper understanding of the studied materials.
