The compositions and structures of the products of the reaction of TaF5 with Ph2P(O)(CH2)2C(O)NМе2 (L) in СН3СN and СН2Сl2 are studied by the 19F and 31Р NMR methods. As the hydrocarbon bridge between the Р=О and С=О donor groups in carbamoylphosphine oxides elongates from –СН2– to (–СН2–)2, the chelation ability of the ligand is retained and the composition of the complexes formed in a solution is determined by the ratio of components. The compositions and structures of the hydrolysis products are studied. Distinctions in the coordination behavior of the considered ligand during complex formation with tantalum pentafluoride and titanium tetrafluoride are studied.
