Unexpected N,N-coordination of the potentially tridentate N,P,N-ligand bis(2-oxazolin-2,5,5-trimethyl)phenylphosphine occurs in Co(II) and Fe(II) complexes, in contrast to the P,N- or N,P,N-coordination modes observed in Pd(II) complexes; this leads to the formation of unprecedented eight-membered ring chelates.
意想不到Ñ,Ñ的潜在三齿-coordination Ñ,P,Ñ -配体双(2-恶唑啉-2,5,5-三甲基)苯基膦存在于Co(II)和Fe(II)配合物中,与Pd(II)中观察到的P,N-或N,P,N-配位模式相反)配合物;这导致空前的八元环螯合物的形成。
