The new coordination modes of bis(1,2,4-diazaphospholyl)methane

Popis výsledku v původním jazyce

The coordination behavior of the polydentate ligand bis(1,2,4-diazaphospholyl)methane (Bdapm) toward group 6 and group 10 metals has been studied. From the reaction with [W(CO)5(NMe3)], three species with different coordination patterns were isolated and characterized. Thus we proved that the polydentate Bdapm ligand could serve as a terminal ?-P, bridging ?2-P,P and chelating ?2-N,N ligand in the complexes [W(CO)5(?-P-Bdapm)], {[W(CO)5]2(?2-P,P-Bdapm)} and {W(CO)4(?2-N,N-Bdapm)}, respectively. The ?2-N,N chelate bonding mode has been also detected in the molybdenum(II) and nickel(II) derivatives [Mo(?3-C3H5)(?2-N,N-Bdapm)(CO)2Cl] and [Ni(acac)2(?2-N,N-Bdapm)]. The reaction of Bdapm with [M(C,N-Ar)Cl] fragment sources [Ar = 2-(N,N-dimethylaminomethyl)phenyl or 2-(N,N-dimethylaminomethyl)ferrocenyl, M = Pd or Pt] gives unstable ?-P bonded species, which are readily converted to the multimetallic complexes {[M(C,N-Ar)Cl]2-?2-P,P-Bdapm}. The different coordination modes of the Bdamp ligand in such compounds were easily distinguished by multinuclear NMR spectroscopy. The crystal structures of five transition metal complexes demonstrating the coordination variability of Bdapm are reported. On inspection of the acquired data it is evident that the stability of the studied species increases in the order of the binding modes ?-P < ?2-P,P < ?2-N,N.
