Abstract
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 laser desorption/ionisation time-of-flight mass spectrometry (LDI-TOF-MS). The spectra contain peaks corresponding to trinuclear clusters together with peaks at higher masses arising from the series of condensed products [MnHn − 1(CO)4n]− (where n = 4–9). These products are believed to have cyclic structures and to be formed by the stepwise insertion of [MH(CO)4] into a metal–metal bond.Keywords
