Crystal structure and magnetic properties of a linear tetranuclear Co(II) cluster.

Polynuclear complexes are an important class of inorganic functional materials and are of interest particularly for their applications in molecular magnets. Multidentate chelating ligands play an important role in the design and syntheses of polynuclear metal clusters. A novel linear tetranuclear Co(II) cluster, namely bis{μ3-(E)-2-[(2-oxidobenzylidene)amino]phenolato}bis{μ2-(E)-2-[(2-oxidobenzylidene)amino]phenolato}bis(1,10-phenanthroline)tetracobalt(II), [Co4(C14H11NO2)4(C12H8N2)2], was prepared under solvothermal conditions through a mixed-ligand synthetic strategy.

Prussian blue electrodeposited on nano Ag-coated multiwalled carbon nanotubes composite for the determination of hydrogen peroxide.

A prussian blue (PB) electrodeposited on nano Ag-coated multiwalled carbon nanotubes (nano Ag-MWNTs) was reported. Also a PB/nano Ag-MWNTs composite modified glass carbon (GC) electrode was used to investigate the electrochemical behavior concerning the reduction of hydrogen peroxide. The experiment results showed that the PB/nano Ag-MWNTs/GC electrode had a wide linear range, a fast response time and high sensitivity toward the electrocatalytic reduction of hydrogen peroxide.

The title complex, [Cu(2)(C(13)H(16)N(3)O(3))(C(12)H(8)N(2))(H(2)O)]NO(3), consists of a nitrate ion and a binuclear Cu(II) unit in which the oxamide ligand has a cis geometry, is fully deprotonated and acts in a bidentate fashion to one Cu(II) atom and in a tetradentate fashion to the other Cu(II) atom. The Cu(II) atom coordination geometries are distorted square-planar and distorted square-pyramidal. In the crystal structure, binuclear complexes and nitrate ions are connected by classical O-H⋯O and non-classical C-H⋯O hydrogen bonds into a three-dimensional framework.
