signals experimentally observed. The acetylide derivative [(μ-H)Fe3(CO)9(CCSiMe3)] was obtained in higher yield. This allowed us to carry out some studies on the reactivity of this derivative. Reactions with piperidine and morpholine showed the easy loss of the hydride group, as a proton, to form anionic derivatives. Therefore, a theoretical study was undertaken to try to determine the pKa in this complex
