摘要：

The new diethyl-{(diphenylphosphino)phenyl}methylphosphonate ligand, rac-Ph2PCH(Ph)P(O)(OEt)(2) 1, has been prepared and coordinated to a Pd(II) metal centre to form PO chelates involving P(M) and P(V) centres, as established by X-ray diffraction of cis-[Pd{Ph2PCH(Ph)P(O)(OEt)(2)-k(2)-P,O }(2)](BF4)(2) 2. Deprotonation of P-bound 1 led to the first anionic beta-phosphonato-phosphine PO chelate, which was characterised by X-ray diffraction in complex [(dmba)Pd {Ph2PC(Ph)PO(OEt)(2)-K-2-P,}].
