摘要
报道8种稀土-吡唑-3,5-二羧酸(P2oA)配合物的合成,通过元素分析、红外、紫光光谱、差热对配合物的结构进行了表征。配合物的通式为:Ln_2L_3·uH_2O(Ln ̄(3+)=La ̄(3+)、Pr ̄(3+)、Nd ̄(3+)、Sm ̄(3+)、Eu ̄(3+)、Tb ̄(3+)、Ho ̄(3+)、Y ̄(3+);L ̄(2-)=P2DA ̄(2-);n=6~11)。
Eight complexes of Rare Earth elements with pyrazole-3,5- dicarboxylic acid were preparedin water solution, The cornposition of the complexes was determined to be Ln_2L_3·nH_2O,[Ln=La(Ⅲ),Nd(Ⅲ),Pr(Ⅲ),Sm(Ⅲ),Eu(Ⅲ),Gd(Ⅲ).Tb(Ⅲ),Ho(Ⅲ)and Y(Ⅲ),L=P2DA ̄(2-)]by el-ementary analysis.The structure and physico-chem ical properties of these complexes were characterizedwith infra-red spectrographic,thermoanalytic,X-ray powder diffraction and fluorometric methods.
