The title compound, [Co(C(2)Cl(3)O(2))Cl(C(12)H(8)N(2))(2)], was obtained by the reaction of trichloro-acetic acid and CoCl(2) in the presence of 1,10-phenanthroline. The Co(II) ion exhibits a distorted octa-hedral geometry, with three N atoms from two 1,10-phenanthroline ligands and the Cl(-) ion in the equatorial plane and one O atom from the trichloro-acetate ligand and one phenanthroline N ...

We describe complexes of ruthenium and europium with rigid, 5'-6-locked 1,10-phenanthroline-containing nucleosides. Both nucleosides were synthesized from condensation of 5-amino-2'-deoxycytidine with the corresponding diketone. The ruthenium nucleoside displayed fluorescence characteristic of polypyridine ruthenium complexes with a maximum at 616 nm and a quantum yield of 0.011. Binding of eur...

Tris-1,10-phenanthroline manganese(II) complex was synthesized by microwave irradiation. The synthesized complex was characterized by UV-visible and FT-IR spectroscopy. Its electrochemical behaviour was examined by cyclic voltammetry (CV). The tris-1,10-phenanthroline manganese(II) complex was used for the electrochemical sensing of catechol. The manganese ion gets reduced as the oxidation of c...

Fluorescence analysis is a simple and highly sensitive method for detection of small amounts biologically active substances. In this study, complexation terbium(III) chelates with 1,10-phenanthroline ascorbic acid (AA) luminescent properties complexes were investigated. The influence pH solubilization by micellar solutions nonionic, cationic, anionic surfactants on fluorescence was studied. que...

In this work, we report the electrochemical response of a family Co(II) complexes, [CoII(L)3]2+ and [CoII(L’)2]2+ (L = 2,2’-bipyridine, 1,10-phenanthroline, 3,4,7,8-tetramethyl-1,10-phenanthroline, 5,6-dimethyl-1,10-phenanthroline, 4,7-diphenyl-1,10-phenanthroline; L’ terpyridine 4-chloro-terpyridine), in presence absence CO2 order to understand role redox potential molecular structure on catal...

Dye-sensitized solar cells transform light into electricity. One commonly used dye is a ruthenium complex. However, the use of has been shown to have several disadvantages. In this study, via singular spectrum analysis using HypSpec software, we determined formation constants and calculated individual electronic spectra species iron(III) with ligands (1,2-diaminoethane, 1,3-diaminopropane, 1,4-...

The asymmetric unit of the title compound, C(12)H(8)N(2)·0.5C(2)H(4)N(2)S(2), contains one 1,10-phenanthroline mol-ecule and a half-mol-ecule of dithio-oxamide, which lies across a crystallographic inversion center. The 1,10-phenanthroline unit is not strictly planar, with dihedral angles between the central benzene ring and the pyridine rings of 1.42 (10) and 1.40 (10)°. In the crystal structu...

The structure of the title complex, [Ag(C(12)H(8)N(2))(C(18)H(15)P)]CF(3)SO(3), is based on a distorted trigonal-planar N(2)P coordination of the Ag(I) ion, provided by two N atoms of the bidentate phenanthroline ligand and one P atom of the triphenyl-phosphine ligand. The phenanthroline ligand and one phenyl ring of the triphenyl-phosphine ligand almost lie in one plane (maximum deviation = 0....

Quantum mechanical calculations of different energies components of 1,10-phenanthroline in ground state were carried out by DFT method , in isolated state and in various solvents to study the effects of solvents on various energy components and global properties. The solvation energy, chemical potential, hardness, electrophilicity of 1,10-phenanthroline were calculated with the help of computed...

We report new divalent osmium complexes that feature strong red metal-to-ligand-charge-transfer (MLCT) phosphorescence and electrophosphorescence. The general formula of the complexes is Os(II)(N-N)(2)L-L, where N-N is either a bipyridine or a phenanthroline and L-L is either a phosphine or an arsine. New polypyridyl ligands synthesized are 4,4'-di(biphenyl)-2,2'-bipyridine (15) and 4,4'-di(dip...
