Abstract

We have investigated the thermal decomposition of Fe(CO)₅ in zeolite (NaX) with unit-cell composition Na_74.5 H_14.1 Al_88.6 Si_103.4 O₃₈₄, and we have used mass spectroscopy, electron spin resonance and Mössbauer spectroscopy to monitor the formation of decomposition products. We have concluded from our studies that the pathway for the formation of crystalline iron clusters considerably depends on vacuum and heat treatment of Fe(CO)₅ in NaX and includes as precursors mononuclear and polynuclear Fe(CO)₃-systems and non-crystalline iron clusters.
