Synthesis And Characterization Of Phosphine Hybrid Pyrazole Metal Tin, Lead Complexes

Phosphine mixed pyrazole and calixarenes are a series ofcompounds with aromatic,and may form a metal complex with metalions.Although their structure is different, but the total of the π systemhole makes the two closely linked, which laid a foundation to formstable metal complex.First of all, Phosphinic heteroaryl pyrazole as a new type ofstructure,not only have the ability to accommodate singleelectron,but also because of its system of6πelectron anion, havingan aromatic, can to form stable metal organic complex compoundwith metal ions,so it plays a key role in the foundation in biochemistry,drugchemical, magnetic materials and superconducting materialsand other aspects.Then this paper design and synthesis of thephospha pyrazole Sn, Pb metal ions to form related metal organiccomplexes, and NMR, elemental analysis and X-ray diffractionanalysis method have been characterized.Second," Calixarene " as the subject of the third generation supramolecular compounds,It has a plurality of hydroxyl groups, andhave caves of π system,so calixarenes and their derivatives can withall the metal ions to form metal complexes, show the goodcoordination ability and the superconducting function.Therefore thisarticle reference of the phospha pyrazole and tert-butylcalix [4] arenejoint chemical properties, further the synthesis and characterizationof the tert-butyl-calix [4] arene bridge even phospha pyrazole, nuclearmagnetic resonance, infrared analysis and the elemental analysiswere used to characterize.Of tert-butyl calix [4] arene unique cavity structure and phosphinehybrid pyrazole combination of single electron capacity,metal ionscoordination of models may be beyond phospha pyrazole ligand andtert-butyl calix [4] arene, and is likely to generate polynuclearcomplexes,which show different from phosphine hybrid pyrazole andtert-butyl calix [4] arene chemical properties,it will open a newsituation for the way to combine heavy metal ion.
