In the title compound, C(15)H(12)N(2)O(2), the seven-membered ring bearing the three methyl-ene C atoms displays a puckered conformation, with the methyl-ene C atoms deviating from the plane of the benzene ring by 0.05 (1), 0.98 (1) and 1.04 (1) Å. The phenanthroline unit is not planar; the dihedral angles between this benzene ring and the other pyridyl rings are 9.62 (4) and 9.31 (4)°. The cry...

In the cation of the title salt, [Ag(C(12)H(6)N(2)O(2))(2)](C(7)H(3)N(2)O(7)), the Ag(I) atom is coordinated in a distorted tetra-hedral geometry by four N atoms from two 1,10-phenanthroline-5,6-dione ligands, while the 3,5-dinitro-salicylate anion has only a short contact [2.847 (6) Å] between one of its O atoms and the Ag(I) atom. The dihedral angle between the two 1,10-phenanthroline-5,6-dio...

In the centrosymmetric binuclear title complex, [Pr(2)(C(9)H(9)O(3))(6)(C(12)H(8)N(2))(2)], the two Pr(III) ions are linked by four 2-phen-oxy-propionate (L) groups through their bi- and tridentate bridging modes. Each Pr(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 PrN(2)O(7) monocapped ...

The title compound, [CdBr(2)(C(12)H(8)N(2))(2)], synthesized by the hydro-thermal reaction of Cd(CH(3)COO)(2)·2H(2)O with NaBr and 1,10-phenanthroline, has the Cd(II) cation coordinated by two Br(-) anions and four N atoms from two 1,10-phenanthroline ligands in a distorted octa-hedral geometry. The crystal packing is stabilized by inter-molecular π-π inter-actions with centroid-centroid distan...

The title complex, [V(2)(C(8)H(7)O(3))(2)O(4)(C(12)H(8)N(2))(2)], is a centrosymmetric dimer formed by two V(V) complex units bridged by two μ(2)-oxido groups. The V(V) atom is six-coordinated by three oxide O atoms, one O atom from a vanillinate ligand and two N atoms from a 1,10-phenanthroline ligand in a significantly distorted octa-hedral geometry. In the crystal structure, weak inter-molec...

The title compound, [Mn(C(5)H(2)N(2)O(4))(C(12)H(8)N(2))(H(2)O)(2)], was synthesized by the reaction of manganese(II) acetate and orotic acid in the presence of 1,10-phenanthroline. The crystal structure exhibits inter-molecular N-H⋯O and O-H⋯O hydrogen bonds . The Mn coordination environment consists of an N(3)O(3) donor set in an octa-hedral geometry.

The title compound, [Cd(2)(C(2)H(3)O(2))(4)(C(12)H(8)N(2))(2)], consists of dimeric units built up around a crystallographic symmetry centre. Each cadmium(II) unit is chelated by a 1,10-phenanthroline (phen) group and two acetate ligands, one of which also acts as a bridge, linking both seven-coordinated cadmium(II) centres. The crystal structure is governed by a single π-π inter-action between...

We have synthesized five novel Ru(ii) phenanthroline complexes with an additional aryl sulfonate ligating substituent at the 5-position [Ru(L)(bpy)2](BF4)2 (1), [Ru(L)(bpy)(SCN)2] (2), [Ru(L)3](BF4)2 (3), [Ru(L)2(bpy)](BF4)2 (4) and [Ru(L)(BPhen)(SCN)2] (5) (where L = 6-one-[1,10]phenanthroline-5-ylamino)-3-hydroxynaphthalene 1-sulfonic, bpy = 2,2'-bipyridine, BPhen = 4,7-diphenyl-1,10-phenanth...

• Iridium complex-based phosphorescent and electrochemiluminescent dual sensors enabled selective detection of GSH. Reduction pdo to phen(OH) 2 upon reaction with GSH triggered PL turn-on ECL turn-off response. Sensing mechanisms were elucidated by DFT calculations cyclic voltammetry. Sensor 1 was applied determination concentrations in human serum. Glutathione (GSH) is the most abundant biolog...
