In the title compound, C12H6N2O2·C2H5OH, the mol-ecule of the 1,10-phenanthroline-5,6-dione is approximately planar, with a maximum deviation of 0.051 (1) Å. In the crystal, mol-ecules are linked by O-H⋯N and weak C-H⋯O hydrogen bonds, forming supra-molecular chains propagating along [110]. π-π stacking inter-actions are observed between the pyridine rings of neighbouring chains, the centroid-c...

In the title compound, [Co(C(17)H(14)O(6))(C(12)H(8)N(2))(H(2)O)](n), the Co(II) atom is coordinated by a monodentate 4,4'-(propane-1,3-diyldi-oxy)dibenzoate (cpp) dianion, a water mol-ecule and a chelating 1,10-phenanthroline (phen) ligand. A symmetry-generated cpp ligand completes the CoN(2)O(3) trigonal-bipyramidal geometry for the metal ion, with the N atoms occupying both equatorial and ax...

The 1,10-phenanthroline-chelated Zn atom in the polymeric title compound, {[Zn(C(7)H(4)O(6)S)(C(12)H(8)N(2))(H(2)O)(2)]·1.5H(2)O}(n), is connected to the sulfonate O atom of one 4-hy-droxy-3-sulfonato-benzoate dianion and to the carboxyl-ate O atom of another dianion. It is also coordinated by two water mol-ecules in an overall octa-hedral environment. The dianion links adjacent metal atoms int...

The 1,10-phenanthroline-chelated Co(II) atom in the polymeric title compound, {[Co(C(7)H(4)O(6)S)(C(12)H(8)N(2))(H(2)O)(2)]·1.5H(2)O}(n), is connected to the sulfonate O atom of one 4-hy-droxy-3-sulfonato-benzoate dianion and to the carboxyl-ate O atom of another dianion. It is also coordinated by two water mol-ecules in a trans-CoN(2)O(4) octa-hedral environment. The dianion links adjacent met...

Objective(s): Due to the rapid increased drug resistance to Plasmodium parasites, an urgent need to achieve new antiplasmodial drugs is felt. Therefore, in this study, the new synthetic phenanthroline derivatives were synthesized with antiplasmodial activity. Materials and Methods: A series of 1,10-phenanthroline derivatives containing amino-alcohol and amino-ether substituents were synthesized...

In a recent publication (1) we reported results obtained by the use of a new analytical procedure for iron in blood plasma. This method, which we find to be more sensitive than those which we have described previously (2-4), depends upon the photoelectric measurement of the red color of the complex formed by ferrous iron with o-phenanthroline. This reaction was first applied, as far as we know,...

The Zn(2+)-chelating metalloprotease inhibitor 1,10-phenanthroline (phenanthroline, 5-150 microM) elicited dose-dependent contraction of the longitudinal and circular (transverse) musculature of adult male schistosomes. At the same concentrations, phenanthroline did not cause contraction of dispersed individual muscle fibres. The phenanthroline-induced contractions were reduced by the inclusion...

tow new compound of type [(chelate)2cu-oh-cu(chelate)2] x3.nh2o, where chelate=1,10-phenanthroline; x=cl¯(n=3.5) and chelate=4,4'-dimethyl-2,2'-bipyridine;  (n=5) have been synthesized and their properties investigated. the complexes show room temperature magnetic moment order of 1.0 b.m. per copper atom. the x-band esr spectrum of powdered samples at room temperature shows typical dm=1 transit...

copper complexes of [cu(phen)(tda)].2h2o(1) and [(phen)2cu(µ-tda) cu(phen)](clo4)2.1.5h2o (2) (where phen is 1,10-phenanthroline and tda2- is thiodiacetate) have been synthesized. both complexes were characterized by elemental analysis, ir, uv–vis spectroscopy and cyclic voltammetry. their solid state structures were determined by the single crystal x-ray diffraction method. complex 1 is mononu...

The only crystals that could be grown from racemic solutions of the PF6(-) salt of the resolvable cation [Ru(2,9-dimethyl-1,10-phenanthroline)2(dipyrido[3,2-d:2',3'-f]quinoxaline)](2+) have translational symmetry only (space group P1), contain nine independent sets of ions, and include numerous independent solvent molecules (11 acetone, one diethyl ether and possibly several water molecules).
