In the title complex, [Ag(NO3)(C10H9N3)4], the nitrate ligand is found to be disordered over two sets of positions, with occupancy factors of 0.473 (5) and 0.527 (5). The Ag(I) ion is located in a square-pyramidal coordination environment formed by four N atoms from four bis-(pyridin-2-yl)amine ligands and one O atom from a nitrate ligand. Weak inter-actions between the Ag(I) ions and the nitra...

a pvc membrane fe(iii) ion selective electrode has been constructed using a new macrocyclic asmembrane carrier.the electrode exhibits a good potentiometric response for fe(iii) over a wideconcentration range 1.0×10-4 to 1.0×10-1m with a slope 19.4±0.5 mv/decade a and a working phrange of 6.5-9.0. it has a fast response time ≤30s.the best performance was observed with themembrance having the 30....

The dinuclear nickel(II) complex [Ni2LmClO4] + , where Lm represents a 24-membered macrocyclic hexaaza-dithiophenolate ligand, reacts with 5-(4-pyridyl)tetrazole (PyrCN4H) to give the [Ni2Lm(PyrCN4)]+ . new was both isolated as perchlorate or tetraphenylborate salts and characterised by elemental analysis IR spectroscopy. structure of [Ni2Lm(PyrCN4)]BPh4 ⋅ MeCN determined single crystal X-ray d...

Formation constants for complexion between alkali metal cations and the crown ether 18C6 in the solvent 2-cyanopyridine at 3OoC were determined from conductance measurements. The method allows for precise determination of these formation constants up to values of K around 10" mol-' dm3. The method also f. permits accurate evaluation of association equilibrium constants between the complex speci...

In the dimeric title complex, [Ag(2)(C(16)H(8)O(8))(C(12)H(8)N(2))(2)] or [Ag(2)(H(2)bta)(phen)(2)] (H(4)bta = biphenyl-2,2',6,6'-tetra-carb-ox-y-lic acid, phen = 1,10-phenanthroline), each Ag(I) ion displays an approximatively planar-trigonal geometry, being surrounded by one chelating phen ligand and one carboxyl-ate O atom from an H(2)bta ligand. Owing to the the presence of crystallographic...

Organic anion template-controlled reactions of benzenepolycarboxylic acids with silver(I) salts resulted in two coordination polymers with distinct structural features based on the argentophilic interaction, one exhibiting a honeycomb layer formed by the fusion of macrocyclic Ag(16) rings and the other furnishing the first example of a Ag(∞) tubular motif.

Dye sensitized solar cells (DSSCs) are considered as one of the most promising alternativerenewable energy sources. In the structure of DSSCs, a photosensitizer composed of transitionmetal complexes is used to harvest light. In this work a binuclear complex containing twopropionitrile pendant arms [ZnLCu(OAC)]PF6 {L = 1, 6- bis (2-cyanoethyl) -2, 5-bis (2-hydroxy3-formyl-5-methylbenzyl)-2, 5- d...

Three novel complexes of Cu(II), Co(II) and Zn(II) using a macrocyclic ligand derived by the condensation of diethylphthalate and benzidine have been designed,synthesized and characterized by UV-Vis.,IR,Mass and Elemental analyses data in order to find out their antifungal activities. The stoichiometry of the complexes has been found to be 1: 1(Metal : Ligand). The analytical data indicate that...

Aziridines are three:membered rings containing one nitrogen atom. They are useful as synthetic intermediates in many organic reactions. Much work has been devoted to synthesizing their analogs, cyclopropanes and epoxides, but little work has been done on the aziridination reaction. This study endeavored to probe the efficiencies of novel copper aziridination catalysts with N3 and 53 macrocyclic...

Constraining a peptide in its bioactive conformation by macrocyclization represents a powerful strategy to design modulators of challenging biomolecular targets. This holds particularly true for the development of inhibitors of protein-protein interactions which often involve interfaces lacking defined binding pockets. Such flat surfaces are demanding targets for traditional small molecules ren...
