The novel complex [μ-(NC)-Fe(CN)3(NO)-μ-(CN)-Cu(ept)]n·4nH2O (ept = N-(2-aminoethyl)- propane-1,3-diamine) was obtained by the reaction of Cu(ClO4)2·6H2O with N-(2-amino- ethyl)propane-1,3-diamine and Na2[Fe(CN)5NO]·2H2O in water. This compound was characterized by IR, UV-VIS and EPR spectroscopies and magnetic measurement. Single-crystal X-ray structure analysis revealed that the title complex has a one-dimensional polymeric structure containing hexacoordinate iron(II) with five cyanide ligands (two of them, in trans position, bridging) and one nitrosyl group, and pentacoordinate copper(II) with N-(2-aminoethyl)propane-1,3-diamine and two sites occupied by bridging cyanide ligands. Magnetic investigation revealed a very weak antiferromagnetic interaction between the copper atoms (superexchange interaction parameter J = -1.7(1) cm-1; H = -JSiSi+1) within the chain through the diamagnetic [Fe(CN)5NO]2- ions.

The electrochemical oxidation of copper in an acetonitrile solution of an aromatic diol (R(OH)2 = catechol, tetrachloro-1,2-dihydroxybenzene, 2,2'-dihydroxybiphenyl) gives soluble copper(I) products which are reduced to copper at a platinum cathode. In the presence of R(OH)2 + L (L = 2,2'-bipyridine, triphenylphosphine, bis(diphenylphosphino)methane (= dppm)), the products are adducts of copper(I) species in which the anionic ligand is [R(O)OH]−. The crystal structure of Cu2[OC6Cl4(OH)]2(dppm)2 is triclinic, with a = 22.418(5) Ǻ b = 1.784(4) Ǻ, c = 13.492(4) Ǻ, α = 61.63(2)°, β = 86.66(2)°, γ = 80.61(2), V = 3093(2) Ǻ3, Z = 2, and space group [Formula: see text] The molecule consists of a Cu—P—C—P—Cu—P—C—P ring, with copper ligated by [R(O)OH]− groups external to this. Intramolecular O—H—O hydrogen-bonding contributes to the stabilization of this novel complex. Key words: Copper, electrochemical synthesis, hydrogen bonding, aromatic diols, crystal structure.

AbstractThe reaction of zinc(II) acetate dihydrate and the tetra-dentate N-Oxo-2-acetylpyridine 4N-methylthiosemicarbazone (H4MLO) produces the novel complex [Zn(C9H11N4OS)2·H2O] (1). The complex crystallizesoin the orthorhombic space group Pbca with a = 15.871(3), b =16.890(3), c = 17.189(3) Å ,V - 4608(1) Å3, Z = 8 . The Zn(II) ion is tetra-coordinated via the thiolate sulfur atom and the azomethine nitrogen atom of two deprotonated ligands. In the solid state, 1 is polymerized via hydrogen bonds with a water molecule of crystallization.

And Behavior

Some novel cobalt diphenylphosphine complexes were synthesized by reacting cobalt(II) chloride with (2-methoxyethyl)diphenylphosphine, (2-methoxyphenyl)diphenylphosphine, and 2-(1,1-dimethylpropyl)-6-(diphenylphosphino)pyridine. Single crystals suitable for X-ray diffraction studies were obtained for the first two complexes, and their crystal structure was determined. The novel compounds were then used in association with methylaluminoxane (MAO) for the polymerization of 1,3-butadiene, and their behavior was compared with that exhibited in the polymerization of the same monomer by the systems CoCl2(PnPrPh2)2/MAO and CoCl2(PPh3)2/MAO. Some significant differences were observed depending on the MAO/Co ratio used, and a plausible interpretation for such a different behavior is proposed.
