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.

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.

Abstract Cadmium metal was oxidized in the presence of N-methylisatin N(4)-cyclohexyl-thiosemicarbazone (HMeIs4Chex) in an acetonitrile solution, which produced a complex of the formula [Cd(MeIs4Chex)2]. The two MeIs4Chex ligands are at an angle close to 90° from each other, and there is hydrogen bonding to two adjacent molecules by the anionic ligands remaining NH groups. The complex crystallizes in the monoclinic space group P21/c with a = 11.820(4), b = 11.491(4), c = 27.834(4) Å, β = 106.82(2)°, V = 3618.7(17) Å3 and Z = 4.

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.

The novel complex, (Ph2PCH2CH2PPh2)2Cu+[(HBpz″3)Mo(CO)3]2Cu− (where pz″ = 3,5-dimethylpyrazolyl), has been synthesized by reacting the (HBpz″3)Mo(CO)3− anionic ligand with CuI in the presence of a stoichiometric amount of Ph2PCH2CH2PPh2. Crystals of (Ph2PCH2CH2PPh2)2Cu+[(HBpz″3)Mo(CO)3]2Cu−•3.5C6H6•CH2Cl2 are triclinic, a = 13.421(1), b = 14.931(3), c = 28.523(5) Å, α = 90.41(2), β = 90.19(1), γ = 104.65(1)°, Z = 2, space group [Formula: see text] The structure was solved by heavy atom methods and was refined by full-matrix least-squares procedures to R = 0.047 and Rw = 0.049 for 8779 reflections with I ≥ 3σ(I). The crystal structure consists of (Ph2PCH2CH2PPh2)2Cu+ cations having irregular tetrahedral coordination geometry about the copper atom (Cu—P = 2.263(2)–2.304(2) Å and P—Cu—P = 88.30(7)–134.62(8)°) and novel [(HBpz″3)Mo(CO)3]2Cu− anions having exact Ci and approximate D3d symmetry. The central Cu atom of the anion is bonded to two Mo atoms in a linear fashion and also interacts with six semi-bridging carbonyl ligands, three from each (HBpz″3)Mo(CO)3− ligand. Average bond lengths and angles for the anion are Mo–Cu = 2.565, Mo—C = 1.955, Mo—N = 2.256, Cu—C = 2.309, C—O = 1.174 Å, Mo—C—O = 171.7° and Cu—C—O = 114.7°.
