摘要: The positive and negative ion ultraviolet laser desorption mass spectra of the trinuclear clusters [M3H3(CO)12] (M = Mn 1 or Re 2) have been recorded using desorption/ionisation time-of-flight spectrometry (LDI-TOF-MS). contain peaks corresponding to together with at higher masses arising from series condensed products [MnHn − 1(CO)4n]− (where n = 4–9). These are believed cyclic structures be formed by stepwise insertion [MH(CO)4] into a metal–metal bond.
