Abstract Reaction of [(en)2Co(H2O)2](ClO4)3 with the dichlorides of nickel, magnesium , and zinc, leads at an pH of ca. 8 to the heterometallic, isomorphous complexes [MII{(OH)2CoIII(en)2}3](ClO4)4Cl·3H2O. The central metal(2 +) cations of these complexes are surrounded octahedraily by three [(en)2Co(OH)2]+ chelate ligands. This has been confirmed by X-ray structure analyses. The cation antipodes of the racemic salts exhibit the conformations Δ (⋀ ⋀ ⋀) / ⋀ (Δ Δ Δ) .

Abstract Metal propionate hydrazinates, M(CH3Ch2COO)2(N2H4)2 where M = Mn, Co, Ni, Zn or Cd, and mixed metal propionate hydrazinates with cobalt, M1/3Co2/3(CH3CH2COO)2(N2H4)2 where M = Mg, Mn, Ni, Zn or Cd, have been prepared and characterized by analytical, magnetic, spectral, thermal and X-ray diffraction studies. The thermal decomposition of the former complexes yields the metal oxides while the latter mixed metal complexes give the corresponding metal cobaltites as the final residue. Formation of metal cobaltites has been confirmed by TG weight loss, IR spectra and X-ray diffraction.

A series of six 3d–4f mixed metal complexes with an Fe2M(μ3-O) triangular core have been synthesized and characterized by X-ray crystallography. Magnetic studies of the compounds reveal a spin frustrated system due to the strong Fe⋯Fe antiferromagnetic interaction.

Mixed Metal Complexes

Complexes of MM?(XCN)4 (M = CoII, NiII; M? = ZnII, CdII, HgII; X = S, Se) with triphenyl-phosphine have been synthesized and characterized by elementary analysis, molar conductance, magnetic moment, infrared and electronic spectral studies. All the complexes are binuclear mixed- metal monomeric bridged of the type (Ph3P)2M(NCX)2M?(XCN)2 except for [Ni(PPh3)4] [Zn(NCS)4] which is cationic-anionic.
