INTRODUCTION. We have previously reported the mass spectra of a single MoFe_3S_4 cubane-like cluster compound (Et_4N)MoFe_3S_4(Et_2NCS_2)_5. Its analogue MoFe_3S_4(C_4HaNCS_2)_5 having the same core structure has rently been synthesized and characterized structurally. In this paper, the results of its mass spectra investigation using an electron impact (EI) ionization mass spectrometer are offered and identified by metastable technique, isotopic
INTRODUCTION. We have previously reported the mass spectra of a single MoFe_3S_4 cubane-like cluster compound (Et_4N) MoFe_3S_4 (Et_2NCS_2) _5. Its analogue MoFe_3S_4 (C_4HaNCS_2) _5 having the same core structure has rently been synthesized and characterized structurally. In this paper , the results of its mass spectra investigation using an electron impact (EI) ionization mass spectrometer are offered and identified by metastable technique, isotopic
