Preferred Abstract (Original): 
The hemilability of the ether-phosphine ligand [Ph2PCH2CH2OMe] was recorded during complexes 1 and 2 synthesis. The structures of both 1 and 2 have been deduced from elemental analysis, IR, EXAF, FAB-mass spectrometry, 1H, 13C{1H} and 31P{1H} NMR spectroscopy. One of the chloride atoms in 1 was abstracted using AgOTf reagent to prepare the mono-cationic O-Ru-P closed 2. By treatment complex 2 with excess amount of NH4Cl in 2-propanol complex 1 was re-prepared. FAB-MS, EXAF and 31P{1H}-NMR served to monitor the hemilability of the ether-phosphine in 1 and 2 at RT.
