    Description / Table of Contents: Tetraphenyl Imidodiphosphate as Ligand in Fluoro Complexes. 2. Fluoro Complexes of PhosphorusTetraphenyl imidodiphosphate forms with PF5 in acetonitrile one pentafluoro (II) and two tetrafluoro complexes (I, III). The imidodiphosphate is monodentately bonded in the pentafluoro complex and it is bidentately coordinated in the tetrafluoro complexes. The constitution and configuration of the complexes are concluded from 19F and 31P n.m.r. data.
    Notes: Imidodiphosphorsäuretetraphenylester, (PhO)2P(O)NHP(O)(OPh)2, bildet mit PF5 in CH3CN einen Pentafluoro- (II) und zwei Tetrafluorokomplexe (I, III). Im Pentafluorokomplex ist der Ligand einzähnig, in den Tetrafluorokomplexen dagegen zweizähnig koordiniert. Alle Konstitutions- und Konfigurationsaussagen zu den Komplexen basieren auf 19F- und 31P-NMR-Untersuchungen.

    Description / Table of Contents: Tetraphenyl Imidodiphosphate as Ligand in Fluoro Complexes. 3. Fluoro Complexes of Niobium, Tantalum, and AntimonyTetraphenyl imidodiphosphate forms with NbF5, TaF5, and SbF5 the addition complexes MF5 · LH and (MF5)2(μ-LH). The imidodiphosphate acts in the latter as bidentately bridging ligand. Furtheron, it reacts with NbF5 and TaF5 by replacing fluoride forming tetrafloro and trifluoro complexes: [MF4(μ-L)]2 and MF3(η2-L)(OPh) or μ-O[MF3(η2-L)]2, resp., (M = Nb, Ta). SbF5 does not form substitution complexes. The constitution and conformation of the complexes have been concluded from n.m.r. spectroscopic data.
    Notes: Imidodiphosphorsäuretetraphenylester, (PhO)2P(O)NHP(O)(OPh)2 (LH), bildet mit NbF5, TaF5 und SbF5 in Acetonitril Additionskomplexe der Zusammensetzung MF5 · LH und (MF5)2(μ-LH). In letzteren fungiert der Ester als zweizähniger Brückenligand. Mit NbF5 und TaF5 reagiert er darüber hinaus unter Fluoridsubstitution zu Tetrafluoro- und Trifluorokomplexen: [MF4(μ-L)]2 und MF3(η2-L)(OPh) bzw. μ-O[MF3(η2-L)]2 (M = Nb, Ta). SbF5 bildet keine Substitutionskomplexe. Die Konstitutions- und Konformationsaussagen beruhen auf NMR-spektroskopischen Befunden.
