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...

The asymmetric unit of the title compound {systematic name: cis-dichloridobis[(3,7-dimethylbicyclo-[3.3.1]non-1-ylmeth-yl)-amine-κN]platinum(II) N,N-dimethyl-formamide solvate}, [PtCl(2)(C(11)H(19)N)(2)]·C(3)H(7)NO, consists of two metrically similar Pt complexes and two dimethyl-formamide solvent mol-ecules. Each Pt(II) center is coordinated by the amine groups of two (1-adamantylmeth-yl)amine...

Based on the complexation between proteins and Cu(II) coupled with the time-resolved chemiluminescence (CL) technique, a highly sensitive and quantitative assay for measuring proteins in solution is described. The complexes of proteins with Cu(II) have a strongly catalytic effect on the luminol-H2O2 CL reaction. Because the CL emission produced by the complexes is much more long-lived than that...

The title compound, (C(2)H(8)N)(4)[Cu(C(6)H(2)N(10))(2)Cl(2)], consists of an anionic complex which is composed of a Cu(II) ion surrounded by four N atoms from two pyrazine-2,3-diylbis(1H-tetra-zol-1-ide) ligands, and two Cl(-) atoms in a trans-Cl(2)N(4) coordination geometry; the Cu(II) atom lies on a site of symmetry 2/m. The Cu-Cl distance of 2.8719 (5) Å is long due to the Jahn-Teller disto...

The title compound, [CuCl2(C12H12N2)] n , was obtained via a DMSO-mediated dehydration of Cu(4,4'-dimethyl-2,2'-bi-pyridine)-copper(II)·0.25H2O. The central Cu(II) atom is coordinated in a distorted trigonal-bipyramidal geometry by two N atoms of a chelating 4,4'-dimethyl-2,2'-bi-pyridine ligand [average Cu-N = 2.03 (3) Å] and three Cl atoms, one terminal with a short Cu-Cl bond of 2.2506 (10) ...

Oscillator strengths for transitions in Cl ii and iii are derived from lifetimes and branching fractions measured with beam-foil techniques. The focus is on the multiplets at 10718 in Cl ii and 10118 in Cl iiiwhose lines are seen in spectra acquired with the Far Ultraviolet Spectroscopic Explorer. These data represent the first complete set of experimental f-values for the lines in the multiple...

In the title coordination polymer, [Hg₄Cl₄(C₂₆H₂₀N₆)](n), one Hg(II) ion is coordinated by four N atoms from the benzylbis((pyridin-2-yl)methyl-idenehydrazone) ligand and two Cl⁻ ions in a very distorted cis-HgCl₂N₄ octa-hedral geometry. The other Hg(II) ion is coordinated in a distorted tetra-hedral geometry by four Cl⁻ ions. Bridging chloride ions link the Hg(II) ions into a chain propagating...

The title complex, [FeZn(C(5)H(5))Cl(2)(C(20)H(14)N(3))]·CH(3)CN, is composed of one Zn(II) atom, one 4'-ferrocenyl-2,2':6',2''-terpyridine (fctpy) ligand, two Cl atoms and one acetonitrile solvent mol-ecule. The Zn(II) atom is five-coordinated in a trigonal-bipyramidal geometry by the tridentate chelating fctpy ligand and two Cl atoms.
