Abstract
The compounds C5H5M[{P(OMe)2O}2H] and C5H5M[{P(OMe)2O}2]Q (M = Ni, Pd; Q = NH4, Tl) react with metal acetylacetonates M'(acac)n and metal chlorides M'Cln to give the tri-and tetranuclear complexes C5H5M[{P(OMe)2O}2]nM' [n = 2 or 3; M' = Co(II), Cu(II), Zn(II), VO, Al(III), Cr(III), Fe(III)]. The mixed-ligand complexes [C5H5Ni{P(OMe)2O}2]2Ni(NH3)2, [C5H5Ni{P(OMe)2O}2]Ni(acac), [C5H5Pd{P(OMe)2O}2]VO(acac), [C5H5M{P(OMe)2O}2]Pd(2-RC3H4) (M = Ni, Pd; R = Me, But) and [C5H5Ni{P(OMe)2O}2]Rh(C8H12) are obtained following similar synthetic routes. Thermolysis of [C5H5Ni{P(OMe)2O}2]2Ni(NH3)2 in vacuo leads to the trinuclear nickel complex [C5H5Ni{P(OMe)2O}2]2Ni. The magnetic properties as well as the IR, NMR, UV and ESR spectra of the new organometallic chelate complexes are discussed.Keywords
