Bismuth vanadate (BiVO(4)), which is a visible-light responsive heterogeneous photocatalyst, was combined with homogeneous ruthenium complexes to increase the overall photocatalytic reactivity for water oxidation with a one-electron oxidant, [Co(III)(NH(3))(5)Cl](2+). Photoinduced electron transfer from the excited state of ruthenium(II) complexes to [Co(III)(NH(3))(5)Cl](2+) affords ruthenium(...

The title compound, [Eu(III)(NO(3))(2)(C(24)H(28)Cl(2)N(6)O(2))]NO(3)·0.5CH(3)OH, is isostructural with the Gd(III) and Ho(III) complexes of the analogous macrocyclic ligand, with both Cl atoms replaced by methyl groups. The Eu atom exhibits a nine-coordinate distorted tricapped trigonal-prismatic coordination geometry. The methanol solvent mol-ecule is disordered about a twofold rotation axis ...

Photoionization of Cl III ions into IV was studied theoretically using the ab initio relativistic Breit–Pauli R-matrix (BPRM) method and experimentally at Advanced Light Source (ALS) synchrotron Lawrence Berkeley National Laboratory. A relative-ion-yield spectrum measured with a photon energy resolution 10 meV. The theoretical study carried out large wave-function expansion 45 levels configurat...

The asymmetric unit of the title complex, [Mn(C(28)H(30)N(2)O(2))Cl(H(2)O)][Mn(C(28)H(30)N(2)O(2))Cl(CH(3)OH)], contains two discrete Mn(III) complexes of a Schiff base ligand, with an N(2)O(2) donor set. Both Mn(III) centers are in a distorted octa-hedral geometry with the N(2)O(2) donor atoms of the tetra-dentate Schiff base dianion in the equatorial plane. The axial positions in the coordina...

Chemiluminescence (CL) of a cyclometallated iridium (III) complex {tris[1-(2,6-dimethylphenoxy)-4-(4-chlorophenyl)phthalazine]iridium(III)} in the presence of potassium permanganate and oxalic acid is reported for the first time. Cysteine exhibits sufficient enhancing effect on the CL generated from the cyclometallated iridium(III) complex, which make it possible for the sensitive detection of ...

Decomposition of 1,4-dimethylnaphthalene endoperoxide, which is the source of singlet oxygen, in the presence of β-diketonates of europium(III), neodymium(III) and ytterbium(III) is accompanied by bright chemiluminescence (CL) in visible and near infra-red spectral region due to characteristic emission from the lanthanides at λmax = 615 and 710 nm ((5)D0→(7)F2 and (5)D0→(7)F4 transitions of Eu(...

In the title dichromium complex, [Cr(2)(C(16)H(14)NO)(3)Cl(3)]·2C(7)H(8), each Cr(III) atom has a distorted octa-hedral coordination geometry. The complex mol-ecule has three six-membered chelate rings formed by hydroxy-butane-imine ligands and the two Cr(III) atoms are bridged by two Cl atoms and one O atom.

A V(III) thiolate complex activated C-Cl bond in dichloromethane via S-based nucleophilic attack. The reaction products, a V(III)-Cl species (major one) and a V(IV) binding to a CH(2) containing ligand (minor one) were obtained. The work demonstrates sulfur donors in the early-transition metal thiolates having strong nucleophilic characteristics.
