Synthese,Structures And Magnetic Properties Of Novel Oximemate-Brided Polynuclear Complexes

With oxime bridges from the tridentate ligand glutarimidedioxime(H2gmdo),complexex[Cu5(gmdo)4](ClO4)2]·CH3OH(1)and[Co3(gmdo)4(H2O)2]ClO4·2CH3OH(2)have been synthesized with Cu(?)ions and Co(?)ion by self-assembly,respectively.Complex 1 was characterized by X-ray single-crystal diffraction?FT-IR?UV-vis?ESI-MS and EPR,magnetic studies revealed antiferromagnetic interaction between Cu(?)ions through oximate-bridge and oxygen-bridge in complex 1.Complex 2 was characterized by X-ray single-crystal diffraction and FT-IR.With oxime bridges from the tridentate ligand 2-hydroxynaphthaldoxime(Naphth-salox),and malonate(MA)as co-ligand,complex[Mn?6O2(napth-salox)6(MA)(CH3OH)4]·3CH3OH(3)has been synthesized with Mn(?)ion by self-assembly.With oxime bridges from the tridentate ligand 3,5-dibromosalicylaldehyde oxime(3,5-dibromo-salox),and 3,5-dimebezoac as co-ligand,complex[Mn?3O(3,5-dibromo-salox)3(3,5-dimebezoac)(H2O)(CH3OH)](4)have been synthesized with Mn(?)ion by self-assembly.With cyanide bridges from the Cs3[W(CN)8]·2H2O,and 1,1,2,2-tetramethyl-ethylenediamine(tmen)as the blocking ligand for Cu(?)ion,a 1D chainlike supramolecular complex[{Cu(tmen)2}2W(CN)a]2[{Cu(tmen)(H2O)}W(CN)8]2(5)based on cyanide and hydrogen bonds has been synthesized.Magnetic studies revealed ferromagnetic interaction between Cu(?)and W(?)through cyanide bridges(J=14.0 cm-1)in complex 5.
