Sažetak:
In order to monitor the progression of the synthesis and the separation of novel mixed-ligand iron complexes containing 1, 10-phenanthroline, 1, 10-phenanthroline-5, 6-dione, and NCS- as ligands all products were mass analyzed by electrospray ionization ion trap MS/MS. The spectra of methanol (MeOH), acetonitrile (ACN), water, and ethanol (EtOH) solutions were collected and the results were compared. It was detected under applied electrospray ionization mass spectrometry (ESI-MS) conditions that MeOH, water, and EtOH formed solvent clusters around the free or complexed 1, 10-phenanthroline-5, 6-dione. Owing to the solvent-ligand hydrogen-bond formation, the solvent-ligand clusters were formed in the polar protic solvents. The number of protic solvent molecules per complex ion in cluster depended on the number of 1, 10-phenanthroline-5, 6-dione ligands in the complex ion. Unlike MeOH, EtOH, or water, ACN was not involved in the formation of the solvent clusters with the iron complexes containing 1, 10-phenanthroline-5, 6-dione as ligand. We also showed that the NCS- group under certain solvent conditions served as a bidentate ligand.
