The hydro-thermal reaction of CoCl(2)·6H(2)O, 1,10-phenanthroline (phen) and K(3)[Fe(CN)(6)] in deionized water yielded the title cyanide-bridged trinuclear cluster, [Co(2)Fe(CN)(8)(C(12)H(8)N(2))(4)]·4H(2)O or [{Co(III)(phen)(CN)(4)}(2){Fe(II)(phen)(2)}]·4H(2)O, which contains two Co(III) centers and one Fe(II) center linked by cyanide bridges. The combination of coordinative bonds, O-H⋯N and ...

Ruthenium polypyridyl complexes have received widespread attention as potential chemotherapeutics in photodynamic therapy (PDT) and in photochemotherapy (PACT). Here, we investigate a series of sixteen ruthenium polypyridyl complexes with general formula [Ru(tpy)(N-N)(L)]+/2+ (tpy=2,2':6',2''-terpyridine, N-N=bpy (2,2'-bipyridine), phen (1,10-phenanthroline), dpq (pyrazino[2,3-f][1,10]phenanthr...

Two new salts of the cation [CuI(dmp)2]+ (dmp is 2,9-dimethyl-1,10-phenanthroline, C14H12N2), namely bis[bis(2,9-dimethyl-1,10-phenanthroline-kappa2N,N')copper(I)] bis(hexafluorophosphate) hemi[bis(4-pyridylmethylidene)hydrazine] acetonitrile solvate, [Cu(C14H12N2)2]2(PF6)2.0.5C12H10N4.C2H3N or [Cu(dmp)2]2(PF6)2.0.5(bpmh).CH3CN [bpmh is bis(4-pyridylmethylidene)hydrazine, C12H10N4], (I), and bi...

The asymmetric unit of the title co-crystal solvate, C(14)H(10)O(4)S(2)·2C(14)H(12)N(2)·C(4)H(8)O, comprises a 2,2'-(disulfanedi-yl)dibenzoic acid mol-ecule, two mol-ecules of 2,9-dimethyl-phenanthroline and a tetra-hydro-furan (THF) solvent mol-ecule. Each end of the twisted diacid [dihedral angle between the benzene rings = 74.33 (17)°] forms a strong O-H⋯N hydrogen bond with a 2,9-dimethyl-p...

The asymmetric unit of the title compound, C24H16N2·0.5CH3OH, is comprised of two independent bathophenanthroline mol-ecules (systematic name: 4,7-diphenyl-1,10-phenanthroline) and one methanol mol-ecule. The bathophenanthroline mol-ecules are not planar as there is a considerable rotation of all terminal phenyl rings with respect to the central phenanthroline units [dihedral angles in the rang...

Electroabsorption studies of ruthenium(II) tris(phenanthroline) show that a substantial change in dipole moment (|Delta&mgr;| = 6.7 +/- 1 D) accompanies ground state to "singlet" metal-to-ligand charge transfer (MLCT) excited-state formation. The change is nearly identical to that reported for the 2,2'-bipyridine analogue (Oh; et al. J.Am. Chem. Soc. 1989, 111, 1130). Since both species lack gr...

In the title compound, [CuCl(2)(C(14)H(12)N(2))], the complex molecule has m symmetry, with the mirror plane oriented parallel to the planar molecule and the ligated Cu(II) atom. The metal centre has a distorted tetra-hedral coordination formed by two N atoms from one 2,9-dimethyl-1,10-phenanthroline ligand and two Cl atoms. There is inter-molecular π-π stacking between adjacent 2,9-dimethyl-1,...

In the structure of the title compound, [Ag(C(2)H(3)O(2))(C(12)H(6)N(2)O(2))]·3H(2)O, the Ag(I) atom is coordinated by both 1,10-phenanthroline-5,6-dione N atoms and one O atom from the acetate anion. The three water mol-ecules are involved in extensive hydrogen bonding to each other and to the acetate O and 1,10-phenanthroline-5,6-dione O atoms. In addition, there are weak C-H⋯O inter-actions.

A new series of pyrrolo[3',4':3,4]pyrrolo[1,2-a]furoquinolines/phenanthrolines and pyrrolo[1,2-a]phenanthrolines were efficiently built up from an 8-hydroxyquinoline derivative or phenanthroline via 1,3-dipolar cycloaddition reaction involving non-stabilized azomethine ylides, generated in situ from the parent furo[3,2-h]quinoliniums/phenanthroliums, in presence of a copper(II) chloride-phenant...
