Gas-phase ligation of Cr+ and Fe+ with 4,9-diazapyrene.
The ligation of Cr+ and Fe+ with 4,9-diazapyrene (DAP) within a Fourier transform mass spectrometer was studied and compared with previous results for the ligands pyrene (Py) and 9-azaphenanthrene (Ap). The results confirm that Fe+, which reacts more slowly but in the same way as Cr+ to bind two Py ligands, behaves quite differently with the nitrogen heterocycles DAP and Ap: it reacts rapidly and it binds three and four of them, respectively.
