چکیده

A dinuclear cobalt capsule [PF(6) subset(CH(3)CN)(2)(Co(2)L(4))][PF(6)](3) (2), (L = bis-benzimidazole-1,3-phenylene) has been prepared using a self-assembly approach. This unique class of cage is perfectly designed to encapsulate weakly coordinated anions, i.e. BF(4)(-) and PF(6)(-)via an Manion weak interaction as illustrated by X-ray and solid-state NMR investigations. Selective anion binding for BF(4)(-) over PF(6)(-) is also observed.

Synthesis and Crystal Structure of Cobalt(III) Complexes of Salen Type Schiff Bases and Tertiary Phosphanes as Ligands

The new [Co(Salen)(PBu3)2]ClO4, [Co(Salen)(PBu3)2]BF4, [Co(Salpn)(PBu3)2]ClO4 and [Co(Salen)(PMe2Ph)2]ClO4 ( where salen = bis(salisylaldehyde)ethylenediimine)) complexes were synthesiszed and chracterized by IR, UV-Vis, 1H NMR spectroscopy and elemental analysis. The IR and 1H NMR spectra cofirmed that the synthesised complexes contain Schiff base ligand, phosphane and conter ion and the eleme...

INFLUENCE OF THE PREPARATION METHOD ON THE STRUCTURE,PHASE FORMATION AND MAGNETIC PROPERTIES OF TEMPLATED CUFE2O4 SPINEL

The synthesis of mesoporous CuFe2O4 spinel by several nanocasting strategies (i.e., multi-step nanocasting, one step nanocasting, modified solid-liquid), in which copper and iron nitrates are used as precursors and Pluronic P123 as surfactant, is explored. We have also checked the effect of pH, citric acid and sodium citrate in multi-step nanocasting method. The modified solid-liquid method whi...

Anion-templated calix[4]arene-based pseudorotaxanes and catenanes.

We present the rational design and anion-binding properties of the first anion-templated pseudorotaxanes and catenanes in which the "wheel" component is provided by a calix[4]arene macrobicyclic unit. The designs and syntheses of two new calix[4]arene macrobicycles, 2 and 3, are presented, and the abilities of these new species both to bind anions and to undergo anion-dependent pseudorotaxane f...

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 struct...

Surface-grafted Europium and Erbium Complexes of the 12-Tungstosilicate Heteropolyoxometalate: A Synthetic and Structural Investigations

The hydrothermal synthesis of two new inorganic-organic hybrid materials in which PDA (PDA = 1,10-phenanthroline-2,9-dicarboxylate) is connected to a well-defined Keggin-type polyoxometalate anion (POM) and a Ln(III) cation (POM = [SiW12O40]4−; Ln = Eu3+ (1), Er3+ (2)), are reported. These hybrids are characterized by elemental analyses, IR spectra and single-crystal X-ray diffraction. Single-c...
