In the centrosymmetric binuclear title complex, [La(2)(C(9)H(9)O(3))(6)(C(12)H(8)N(2))(2)], the two La(III) ions are linked by four 2-phen-oxy-propionate (L) groups in bi- and tridentate bridging modes. Each La(III) ion is nine-coordinated by one 1,10-phenanthroline mol-ecule, one bidentate chelating carboxyl-ate group and four bridging carboxyl-ate groups in a distorted LaN(2)O(7) monocapped s...

An enantioselective sulfimidation of 3-thiosubstituted 2-quinolones and 2-pyridones was achieved with a stoichiometric nitrene source (PhI=NNs) silver-based catalyst system. Key to the success reaction is use chiral phenanthroline ligand hydrogen bonding site. The enantioselectivity does not depend on size two substituents at sulfur atom but only binding properties heterocyclic lactams. A total...

In the last decade, progress has been made in G-quadruplex (G4) ligands development, but for most compounds, ligand binding mode is speculative or based on low resolution methods, with its discovery structure-based approaches. Herein, we report synthesis of small (MW < 400 Da) heterocycle containing different aromatic scaffolds, such as phenyl, quinoline, naphthalene, phenanthroline and acri...

a new sensitive, simple and rapid method for determination of methotrexate (mtx) was developed based on quenching effects of mtx on the fluorescence intensity of tb3+-1,10-phenanthroline complex. the fluorescence intensity was measured with excitation wavelength of 300 nm and emission wavelength of 545 nm and the quenched fluorescence intensity is proportional to the concentration of mtx in tris...

In the title compound, [Co(C(5)H(9)O(2))(2)(C(12)H(8)N(2))(H(2)O)], the Co(II) atom is coordinated in a distorted octahedral environment by three carboxyl O atoms of two trimethyl-acetate ligands, one aqua O atom and two N atoms from 1,10-phen-anthroline. The crystal structure is stabilized by O-H⋯O hydrogen bonds and π-π stacking inter-actions [inter-planar distance between inter-digitating 1,...

In the centrosymmetric binuclear title complex, [Tb(2)(C(9)H(9)O(3))(6)(C(12)H(8)N(2))(2)], the two Tb(III) ions are linked by four 2-phen-oxy-propionate (L) groups through their bi- and tridentate bridging modes. Each Tb(III) ion is nine-coordinated by one 1,10-phenanthroline mol-ecule, one bidentate carboxyl-ate group and four bridging carboxyl-ate groups in a distorted TbN(2)O(7) monocapped ...

A series of new star-shaped trinuclear Ru(II) complexes of imidazo[4,5-f][1,10]phenanthroline derivatives, [{Ru(bpy)(2)}(3){μ-mes(1,4-phO-Izphen)(3)}](ClO(4))(6)·4H(2)O (6), [{Ru(phen)(2)}(3){μ-mes(1,4-phO-Izphen)(3)}](ClO(4))(6)·3H(2)O (7), [{Ru(bpy)(2)}(3){μ-mes(1,2-phO-Izphen)(3)}](ClO(4))(6)·4H(2)O (8), and [{Ru(phen)(2)}(3){μ-mes(1,2-phO-Izphen)(3)}](ClO(4))(6)·3H(2)O (9) [mes(1,4-phO-Izph...
