希土水杨酸与8─羟基喹啉三元配合物研究

STUDIES ON TERNARY COMPLEXES OF RARE EARTH WITH SALICYLIC ACID AND 8-HYDROXYQUINOLINE

合成了六种希土（ＲＥ）－水杨酸（Ｈ２ｓａｌ）－８－羟基喹啉（Ｈｈｑ）三元固体配合物，其通式为ＲＥ（Ｈｓａｌ）２·ｈｑ（ＲＥ＝Ｙ，Ｌａ，Ｎｄ，Ｓｍ，Ｈｏ，Ｅｒ）．通过元素分析、摩尔电导、ＩＲ、Ｆａｒ－ＩＲ、ＵＶ－Ｖｉｓ、ＴＧ－ＤＴＡ分析，研究了配合物的组成、性质和成键特性．通过抑菌试验表明配合物对于霉菌具有抑真菌能力．

ix new solid complexes of rare earth with salicylic acid(H2sal)and 8-hydroxyquinoline (Hhq) were prepared. These complexes all have the composition of RE(Hsal)2·hq(RE=Y,La,Nd,Sm,Ho,Er;Hsal=C7H5O3;hq=C9H6NO). The compositions.propertics and bonding specificity between RE(3+) and ligands have been confirmed by clemental analysis,molar conductancc,IR,Far-IR,UV,Vis and TG-DTA mcasurcmcnts.Results from fungistatic testing indieated that these complexes all have fungistatic ability on molds.
