Seven-coordinate, pentagonal-bipyramidal (PBP) complexes [Ln(bbpen)Cl] and [Ln(bbppn)Cl], in which Ln = Tb3+ (products I II), Eu3+ (III IV), Gd3+ (V VI), with bbpen2– N,N′-bis(2-o...

In the title compound, [Fe(C(20)H(14)N(4)O(2))Cl], the Fe(III) ion is in a distorted square-pyramidal environment, with two pyridine and two deprotonated amide N atoms in the basal plane and the Cl ion in the apical position. The Fe(III) ion is displaced from the basal plane of the square- pyramid towards the apical Cl atom by 0.2942 (4) Å. The mol-ecules are linked into a three-dimensional net...

The asymmetric unit of the title complex salt, [Cr(C10H24N4)(NH3)2][ZnCl4]Cl·H2O, is comprised of four halves of the Cr(III) complex cations (the counterparts being generated by application of inversion symmetry), two tetra-chlorido-zincate anions, two chloride anions and two water mol-ecules. Each Cr(III) ion is coordinated by the four N atoms of the cyclam (1,4,8,11-tetra-aza-cyclo-tetra-deca...

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.
