چکیده
The reaction of 4-ethynyl-pyridine with tert-butyl lithium followed by its addition to (Me3tacn)RhCl3 affords the facial octahedral complex (Me3tacn)Rh(CCPy)3, condensation of which with the square planar complex cis-(DCPE)Pt(NO3)2 results in a self-assembled trigonal bipyramidal cage with Rh(III) and Pt(II) atoms occupying the vertices.

متن کاملSynthesis and characterization of the Pt/SiO2 nanocomposite by the sol-gel method
The silica supported platinum nanoparticles was synthesized by using the sol-gel method. The possibility of using diamminedinitro platinum (II) as Pt precursor and effect of metal precursor concentration on the final Pt nanoparticle size was investigated. A stable silica sol was prepared via hydrolysis of tetraethyl orthosilicate (TEOS) as a metal alcoxide and condensation reaction. Subsequentl...

Metal—Polyaniline nanocomposites such as Platinum-Polyaniline nanocomposite is prepared by insitu oxidative polymerization of aniline and reduction of Pt+4 ions into Pt nanoparticles. Thepolymerization of aniline was carried out in the presence of 1(2PtCN6 [Potassium Hexa CyanoPlatinate (IV)] as oxidizing agent. During the reaction aniline monomers undergo oxidation andform polyaniline (PANT) w...

This study reports a green approach to synthesis of monometallic platinum nanoparticles (Pt NPs) and bimetallic aurium@platinum nanoparticles (Au@Pt) using aqueous leaf extract of Carica papaya as a reducing and stabilizing agent. The nature and morphology of as-synthesized PtNPs and bimetallic Au@Pt NPs were characterized using UV/vis spectroscopy (UV–vis), high resolution transmission electro...
متن کاملSynthesis of a rhodaazacyclopropane and characterization of its radical cation by EPR spectroscopy.
Cyclopropane and its derivatives (ER2)3 (E=C, Si, Ge, Sn), bicyclobutanes, and other strained hydrocarbons have remarkably low oxidation potentials when compared to their unstrained linear counterparts. Can this property be translated to transition-metal complexes, such that small rings incorporating the transition metal lead to more facile oxidation? With this question in mind, we characterize...
