内容記述 | The cyclotriphosphate ion as a nBu4N salt reacts with[Cp*TaCl4](Cp*= η5-C5Me5) in CH2Cl2 at room temperature to give the anionic cyclotriphosphato complex (nBu4N)[Cp*TaCl(OH)(P3O9)](1) in 24% yield. The analogous niobium complex (PPN)[Cp*NbCl(OH)(P3O9)] (2) is synthesized by the reaction of PPN cyclotriphosphate (PPN=(PPh3)2N+) with [Cp*NbCl4] under similar conditions (42% yield). X-ray diffraction studies of 1-0.5Et2O and 2-CH2Cl2 have shown that these complexes adopt a distorted octahedral structure in the solid state, where the three axial oxygen atoms of the cyclotriphosphato ligand occupy the fac positions, and the Cl, OH, and Cp* ligands are located at the other coordination sites. The M-OH bond distances (M=Ta, 1.873(5)A;M=Nb,1.963(3)A) suggest that the Ta-OH bond has a considerable double-bond character, while the π-donation from the OH ligand to the niobium center is weak. The complex anion in 1-0.5Et2O forms a hydrogen-bonded dimeric structure. On the other hand, the complex anion in 2-CH2Cl2 is engaged in relatively strong CH…O hydrogen bonds with CH2Cl2 molecules. | |||||
