  日期：2006.9

  The synthesis and the characterization of several mono- and polymetallic derivatives of 1,10-phenanthroline-5,6,-dione (1) are presented. The reaction of 1 with M(CO)(6) (M = Cr, Mo) gives compounds of general formula M(O, O'-C12H6N2O2)3, M = Cr (2), Mo (3). Compound 3 is also obtained starting from Mo(eta(6)-CH3C6H5)(2), whereas the reaction of Cr(eta(6)-CH3C6H5)(2) with 1 affords the ionic derivative [Cr(eta(6)-CH3C6H5)(2)][C2H6N2O2] (4), which has been studied by EPR spectroscopy and DFT calculations. FeCl2(N,N'-C12H6N2O2)(2) (6), is obtained by thermal decomposition of [Fe(N,N'-C12H6N2O2)(3)]Cl-2 (5).Polymetallic compounds of general formula Cr[O,O'-C12H6N2O2-N,N'-MCl4](3),containing chromium and a Group 4 element M=Ti (7), Zr (8), Hf (9), are prepared from Cr(O,O'-Cl2H6N2O2)(3) and the corresponding MCl4 or MCl4DME. Polynuclear derivatives of iron and chromium of formula [Fe(N,N'-C12H6N2O2-O,O'-CrCl2(THF)(2))(3)][PF6](2) (10), and Cr[O,O'-C12H6N2O2-NN'-FeCl2(THF)](3) (11), are obtained by the reaction of [Fe(N,N'-C12H6N2O2)(3)][PF6](2) with three equivalents of CrCl2(THF)(2) and from Cr(O,O'-Cl2H6N2O2)3 and FeCl2(THF)(1.5), respectively. Compound 11 reacts with 1 (3 equivalents in SYM-C2H2Cl4 or 6 equivalents in ethanol) to give Cr[O,O'-C12H6N2O2-N,N'-FeCl2(N,N'-C12H6N2O2)](3) (12), and [Cr(O,O'-Cl2H6N2O2-N,N'-Fe(N,N'-C12H6N2O2)(2))(3)]Cl-6 (13), respectively.

  Titanium tetrachloride reacts with 2,6-bis[(1-phenylimino)ethyl]pyridine, 1, and 2,6-bis[1-(2,6-diisopropylphenylimino)ethyl]pyridine, 2, giving the adducts of general formulae [Ti(1)Cl3]Cl, 3, and [Ti(2)Cl3]Cl, 6, the latter through the intermediacy of the covalently bonded [Ti(2)Cl4], 4. Heating 6 leads to reduction to the titanium(III) derivative [Ti(2)Cl3], 12, the latter characterized by X-ray
