Using modified solvothermal conditions (longer cooling time), beside previously characterized dark-green crystals of [Ni(C(4)H(2)O(4))(C(12)H(8)N(2))] (main product), a few light-green crystals of the polymeric title compound, catena-poly[[aqua-(1,10-phenanthroline-κ(2)N,N')nickel(II)]-μ-fumarato-κ(2)O:O'-[aqua-(1,10-phenanthroline-κ(2)N,N')nickel(II)]-μ-fumarato-κ(4)O,O':O'',O'''], [Ni(C(4)H(2...

It has previously been demonstrated that phenanthroline-based ligands used to make gold metallotherapuetics have the ability to exhibit cytotoxicity when not coordinated to the metal center. In an effort to help assess the mechanism by which these ligands may cause tumor cell death, iron binding and removal experiments have been considered. The close linkage between cell proliferation and intra...

Isolated rabbit hepatocytes were incubated with [35S]methionine to label intracellular pools of apolipoprotein B (apo-B). The cells were then reincubated with an excess of unlabelled methionine in the presence of oleate or protease inhibitors and the intracellular sites of accumulation of radiolabelled apo-B and the mass of apo-B were determined by isolation and analysis of subcellular fraction...

The synthesis and characterization of copper complexes of the phenanthroline based bridging ligands, 9-methyl-2-(2-[4-[2-(9-methyl-1,10-phenanthrolin-2-yl)ethyl]phenyl]ethyl)-1,10-phenanthroline, 1, and 1,12-bis(9-methyl-1,10-phenanthroline-2-yl)dodecane, 2, are presented. Whereas in the first case a discrete dimeric complex [Cu(2)(1)(2)](BF(4))(2) was formed, in the latter, a coordination poly...

Crystals of the title compound, C(12)H(8)N(2)·C(7)H(8)O(2), were obtained during cocrystallization experiments of a compound with two hydrogen-bond donors (2-hydroxy-benzyl alcohol) with another compound containing two hydrogen-bond acceptors (phenanthroline). Unexpectedly, the two mol-ecules do not form dimers with two O-H⋯N hydrogen bonds connecting the two mol-ecules. However, one of the hyd...

A highly emissive copper(I) complex bearing (4R,5R)-(-)-4,5-bis(diphenylphosphinomethyl)-2,2-dimethyl-1,3-dioxolane (diop) and 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline (dmpp), [Cu(dmpp)(diop)]PF6 (1·PF6), was newly synthesized. The quantum yield of the luminescence of 1·PF6 in degassed dichloromethane is 0.38, which is one of the highest values among all copper(I) complexes bearing two bid...

In the centrosymmetric dinuclear title complex, [Cu(2)(C(5)H(6)O(4))(2)(C(12)H(18)N(2))(2)(H(2)O)(2)], the Cu(II) atom displays a dis-torted square-pyramidal coordination environment with the basal plane occupied by two phenanthroline N atoms and two O atoms from different glutarate dianions while a water mol-ecule is located at the apical position. Of the two water H atoms, one is engaged in a...

In the title binuclear complex, [Fe(2)(C(8)H(7)O(2))(4)(C(12)H(8)N(2))(2)(H(2)O)], the Fe(II) ion is six-coordinated by three carboxylate O atoms from three 4-methyl-benzoate ligands, two N atoms from two 1,10-phenanthroline ligands and one bridging aqua ligand in a distorted octa-hedral geometry. The coordinated water mol-ecule acting as the bridging ligand is located on a twofold axes and the...

The sterically shielded terpyridine was prepared, both as a new ligand and as part of the four-station nanoscaffold . Mixing of terpyridine , the parent phenanthroline and the shielded phenanthroline in the presence of Zn(2+) (1 : 1 : 1 : 1) furnished quantitatively the inverse HETTAP complex [Zn()()](2+) by self-sorting, while in the presence of Cu(+) the HETPHEN complex [Cu()()](+) was prefer...
