The title compound, [Cu(NO3)(C12H8N2)2]NO3·C7H6O5·H2O, consists of a mononuclear complex cation with the central CuII atom in a distorted trigonal-bipyramidal coordination sphere. Two N atoms of two 1,10-phenanthroline ligands occupy the axial sites, and the remaining N atoms of the two ligands, as well as one nitrate O atom the equatorial positions. One mol-ecule each of gallic acid and water ...

The electron affinities (EAs) of a training set of 19 metal-salen compounds were calculated using density functional theory. Concurrently, the experimental reduction potentials for the training set were measured using cyclic voltammetry. The EAs and reduction potentials were found to be linearly correlated by metal. The reduction potentials of a test set of 14 different metal-salens were then m...

Pulse-dipolar EPR is an appealing strategy for structural characterization of complex systems in solution that complements other biophysical techniques. Significantly, the emergence genetically encoded self-assembling spin labels exploiting exogenously introduced double-histidine motifs conjunction with CuII-chelates offers high precision distance determination nonpermissive to thiol-directed l...

The quinquedentate macrocyclic ligand cyclo-6,6'-[1,9-(2,5,8-trithianonane)]-2,2'-bipyridine ([15]aneS3bpy = L), containing two pyridyl nitrogens and three thiaether sulfurs as donor atoms, has been synthesized and complexed with copper. The CuII/IL redox potential, the stabilities of the oxidized and reduced complex, and the oxidation and reduction electron-transfer kinetics of the complex rea...

The crystal structure and the magnetic properties of a heterodinuclear complex, [LCu(Me2CO)Gd(NO3)3]2 (L=N,N’-bis(2-hydroxy-3-methoxybenzylidene)-1,3-diaminopropane) are reported: [(C19H20N2O4)Cu(C3H6O)Gd(NO3)3]2, triclinic, space group P1, with a = 12.118.3(9), b = 13.562(3), c = 9.391(3) Å, α = 93.03(3), β = 107.65(2), γ = 73.07(2)◦ , V = 1406.0(7) Å3, Z = 1. The crystal structure consists of...

Two new small-molecule enzyme mimics of carbonic anhydrase were prepared and characterized. These complexes contain the salen-like ligand bis(hydroxyphenyl)phenanthroline. This ligand is similar to the salen-type ligands previously incorporated into carbonic anhydrase mimics but contains no hydrolyzable imine groups and therefore serves as a promising ligand scaffold for the synthesis of a more...

Two new one-component aluminium-based catalysts for the reaction between epoxides and carbon dioxide have been prepared. The catalysts are composed of aluminium-salen chloride complexes with trialkylammonium groups directly attached to the aromatic rings of the salen ligand. With terminal epoxides, the catalysts induced the formation of cyclic carbonates under mild reaction conditions (25-35 °C...

In the title dinuclear salen-type complex, [CuEu(C(22)H(24)N(2)O(4))(NO(3))(3)(CH(3)OH)], the Cu(II) ion is five-coordinated to two imine N atoms and two phenolate O atoms and one O from the bridging nitrate group. The Eu(III) ion is ligated to three nitrate groups, four O atoms from the salen-type ligand and one methanol mol-ecule, leading to a distorted tenfold coordination for the rare earth...
