Pentacyanonitrosyl salts have raised increasing interest because of their potential use as charge spin crossover keys or hydrogen storage plataforms. Although several studies including the crystallographic, thermal and vibrational properties of a series of hydrated and anhydrous alkaline and alkaline-earth pentacyanonitrosylferrate, [Fe(CN)5 NO]2- , have been previously reported (1-3 and references therein) much work should be performed to understand their thermal stability and electronic behaviour. In this work, we present a systematic and extensive investigation of the thermal decomposition of the different complexes with general formula Am [B(CN)5 NO]n where A= K, Co, B= Fe, Cr, Mn, m=1,3 and n= 1,2 using XAS (EXAFS, XANES), XRD. XAS experiments were performed at Co, Cr, Fe and Mn K-edges. Our main purpose is to contribute to the study to their alkaline and transitions metals salts focusing on the thermal evolution of the local and electronic structure observed from the metallic sites.
