In methanol, the reaction of stoichiometric amounts of Mn(OAc)(2)·4H(2)O and the ligand H(3)hpnbpda [H(3)hpnbpda=N,N'-bis(2-pyridylmethyl)-2-hydroxy-1,3-propanediamine-N,N'-diacetic acid] in the presence of NaOH, afforded a new water soluble dinuclear manganese(II) complex, [Mn2(hpnbpda)(μ-OAc)] (1)....

Two new water-soluble hetero- and homometallic tetranuclear clusters, Na4[Cu2Zn2(ccdp)2(μ-OH)2]·CH3OH·6H2O (1) and K3[Cu4(ccdp)2(μ-OH)(μ-OH2)]·14H2O (2), have been synthesized in methanol-water at room temperature by exploiting the flexibility, chelating ability, and bridging potential...

Sugar-metal ion interactions in aqueous medium are involved in many biochemical processes such as the transport and storage of metals, the function and regulation of sugar-metabolizing metalloenzymes, the mechanism of...

We have studied the binding interactions of biologically important carbohydrates (D-glucose, D-xylose and D-mannose) with the newly synthesized five-coordinate dinuclear copper(II) complex, [Cu(2)(hpnbpda)(μ-OAc)] (1) and zinc(II) complex, [Zn(2)(hpnbpda)(μ-OAc)] (2) [H(3)hpnbpda=N,N'-bis(2-pyridylmethyl)-2-hydroxy-1,3-propanediamine-N,N'-diacetic...

The investigation of the sugar-metal ion interactions remains one of the main objectives of carbohydrate coordination chemistry because the interactions between metal ions and carbohydrates are involved in many biochemical...

Two novel, a mono- and a heptanuclear, zinc complexes have been prepared and characterized by exploiting the flexibility and chelating and bridging ability of a new carboxylate- and amide-rich dinucleating...

Zinc complexes of a new symmetric dinucleating ligand, N,N'-Bis[2-carboxybenzomethyl]-N,N'-Bis[carboxymethyl]-1,3-diaminopropan-2-ol (H5ccdp) with mixed donating groups, have been studied in the solid state as well as in solution. In methanol, the reaction...

The synthesis and characterization of two new dinuclear nickel(II) complexes, namely bis{mu-3-[2-(dimethylamino)ethylimino]butan-2-one oximato}dinickel(II) bis(perchlorate) acetonitrile solvate, [Ni2(C8H16N3O)2](ClO4)2 x CH3CN, (I), and bis{mu-3-[2-(dimethylamino)ethylimino]-3-phenylpropan-2-one oximato}dinickel(II) bis(perchlorate), [Ni2(C13H18N3O)2](ClO4)2, (II), are reported. Single-crystal X-ray...

A novel double-stranded tetranuclear helicate composed of a pair of [Cu(II)(2)] dimers has been prepared and characterized by exploiting the flexibility, chelating ability and bridging potential of a hexadentate bis-oximate...

In methanol, the reaction of Cu(ClO(4))(2).6H(2)O and the hexadentate amine phenol ligand (H(2)bahped) in the presence of triethylamine affords a tetranuclear copper(II) complex having the formula [Cu(4)(mu(4)-O)(bahped)(2)](ClO(4))(2). The X-ray structure...
