摘　　要：本文合成了铽(Ⅱ)与1,5-双-(1′-双-(1′1-苯基-3′-甲基-5′-氧代吡唑-4′-基)-戊二酮-[1.5]和溴化十六烷基三甲铵、溴化十六烷基吡啶及溴化铵三元固体配合物,进行了元素分析、红外吸收光谱、紫外吸收光谱、荧光光谱、热重和差热分析,以及溶解性和摩尔电导测定,并与有关的配合物进行了比较.Three complexes have been synthesised and characterized by elementalanalysis,molar conductance,IR spectra,UV-visible spectra,thermoanalysisfluorescence spectra etc.Compositions of these complexe are NH_4[Tb(BPMPPD)_2],CTA[Tb(BpMPPD)_2]and CP[Tb(BPMPPD)_2],[CTA=positive ion of cetyl trimethylammonium bromide,CP=positive ion of cetylpyridin bromide,BPMPPD=1,5-bis-(1'=pheny 1-3'-methyl-5'-Pyrazolon-4')-1,5-pentanedione].These complexes are close to 1:1 type electrolyte inalcohol solution.The infrared spectra of complexes show that BPMPPDacts as a tetraden-tate ligand which combines with terbium ion throughthe oxygen of C=O and C-O.The coordination number of the ter-biumion in the complexes is eight.Results of thermo-analysis show that thecomplexes are thermally stable up to 300 C.Fluorescence spectra showthat CTA[Tb(BPMPPD)_2)]has very strang and characteristic fluorescence;for this reason,it is possible that the content of trace terbium ion bemeasured by fluorescence analysis.
