Engineering coordination assemblies of dinuclear CuII complexes.
Hybrid organic-inorganic coordination assemblies are synthesized using modified aminocarboxylic acid ligands as the structure-directing agents. The synthetic approach results in two novel dinuclear copper(II) complexes, K2[CuII(hnida)]2.2H2O (1) and K4[CuII(chnida)]2.4H2O.4MeOH (2) that assemble in the presence of suitable counterions into a densely packed hexagonal array or an open-framework s...
متن کاملSynthesis, crystal structure, DNA binding and cleavage activities of oximato bridged cationic dinuclear copper(II) complex having labile ligands
Oximato bridged dinuclear copper(II) complex [Cu(L)(CH3OH)]2(ClO4)2 with an oxime-Schiff base ligand, viz. 3-[2-[(dimethylamino)ethyl]imino]-2-butanoneoxime (HL), has been synthesized and structurally characterized. The dinuclear copper(II) complex crystallizes in monoclinic space group P21/n with the unit cell parameters, a = 13.3564(9) Å, b = 12.0821(8) Å, c = 17.5045(11) Å, β = 90.097, V = 2...

Few novel cobalt(II) and copper(II) complexes [M(fmp)3]Cl2, [M(fmp)(bpy)2]Cl2,[M(fmp)(phen)2]Cl2 and [M(fmp)(phen)(bpy)]Cl2 (fmp = 3-furan-2-ylmethylene-pentane-2,4-dione, phen = 1,10-phenanthroline, bpy = 2,2'-bipyridine) have been synthesized andcharacterized by elemental analyses, molar conductance, magnetic susceptibility measurements,IR, electronic, EPR, mass spectra and cyclic voltammetri...
متن کاملSynthesis, characterization, DNA binding and cleavage, BSA interaction and anticancer activity of dinuclear zinc complexes.
Three new zinc(II) complexes: [Zn(2)(L(1))(2)Cl(2)](ClO(4))(2)·C(2)H(5)OH (1) and [ZnL(2)X(4)]·2CH(3)CN (X = Br for 2, Cl for 3), utilizing two new and interrelated di-nucleating polypyridyl ligands (L(1), L(2)), have been synthesized and characterized by using various physico-chemical techniques. The interactions of three complexes with CT-DNA have been explored by using absorption, emission a...
متن کاملpH luminescence switch, DNA binding and photocleavage, and cytotoxicity of a dinuclear ruthenium complex.
The ground- and excited-state acid-base properties of [Ru2(bpy)4(H2bipt)]Cl4 1 {bpy = 2,2'-bipyridine, H2bipt = 2,5-bis[1,10]phenanthrolin[4,5-f]-imidazol-2-yl)thiophene} are investigated by emission and UV-visible absorption spectrophotometric pH titrations. The DNA binding properties of 1 are studied by means of DNA viscosity and optical spectroscopic techniques of UV-visible absorption and e...
