A series of 3-[2'-(Substitutedbenzylideneamino)phenyl]-2-methyl-6-substituted quinazolin-4-ones (5-10), 3-[2'-(3(″)-chloro-2(″)-oxo-4(″)-substitutedphenylazetidin-1(″)-yl)phenyl]-2-methyl-6-substitutedquinazolin-4-ones (11-16), and 3-[2'-(2(″)-substitutedphenyl-4(″)-oxo-1(″),3(″)-thiazolidin-3(″)-yl)phentl]-2-methyl-6-substitutedquinazolin-4-ones (17-22) have been synthesized in the present stu...

New tris(2,2′-bipyridine)-type ruthenium(II) complexes with L-lysine-containing side chains form gels by hierarchical assembly of hydrogen bonded fibers in some organic solvents. These Ru(II) complex aggregates are more efficient photosensitizers for reduction of methyl viologen than Ru(bpy)3 in the presence of triethanolamine, a sacrificial electron donor. The increased rate of reduced viologe...

The photoinduced oxidation of tetra(N-methyl-4-pyridyl)porphyrinmanganese(III) has been achieved in homogeneous solution. The manganese porphyrin was used as an electron donor in a three-component system with tris-(2,2'-bipyridine)ruthenium(II) as the photosensitizer and chloropentaamminecobalt(III) as the electron acceptor. The photooxidized manganese porphyrin is unstable in aqueous solution,...

In the title compound, [Zn(C(8)H(7)O(2))(2)(C(10)H(8)N(2))], the Zn(II) atom is coordinated by four O atoms from two chelating 4-methyl-benzoate ligands and two N atoms from a 2,2'-bipyridine ligand, displaying a disordered octahedral geometry. C-H⋯O hydrogen bonds connect the complex mol-ecules into a three-dimensional supra-molecular structure.

A series of stable platinum complexes containing closo-carborane cages in a 'carrier group', which could be potentially utilized for boron neutron capture therapy (BNCT), was successfully synthesized and characterized by various spectroscopic methods. Two ortho-closo-carborane cages were connected to the 3,3' or 4,4'-positions of 2,2'-bipyridine through ester bonds to give three carborane-linke...

The title compound, [Ru(C(10)H(8)N(2))(2)(C(13)H(7)N(3)S)](PF(6))(2)·CH(3)CN, was synthesized by the reaction of thio-phosgene and bis-(2,2'-bipyridine)(1,10-phenanthrolin-5-amine)ruthenium(II) bis-(hexa-fluoridophosphate). The Ru(II) atom adopts a slightly distorted octa-hedral RuN(6) coordinaton formed by four N atoms of two bipyridine ligands and by two N atoms of the 1,10-phenantroline liga...

The Co(III) atom in the title compound, [Co(C(12)H(6)N(2)O(4))(C(12)H(7)N(2)O(4))], is six-coordinated in a distorted octa-hedral geometry by four N atoms and two O atoms of the chelating 2,2'-bipyridine-6,6'-dicarboxyl-ate and 6'-carb-oxy-2,2'-bipyridine-6-carboxyl-ate ligands. Intermolecular O-H⋯O hydrogen bonds and face-to-face π-stacking inter-actions [centroid-centroid distance = 3.6352 (1...
