3,3′-(1,4-苯二甲烯基)-双-2,4-戊二酮及其银(Ⅰ)配合物的合成及晶体结构

摘要

The compound 3,3' -[ 1,4-phenylenebis (methan- l-yl- 1-ylidene)]dipentane-2,4-dione (L) was synthesized from condensation reaction of acetylacetone with terephthalic aldehyde,and further AgBF4 react with L to give the coordination polyer {[AgL]BF4}n. the compounds are characterized by 1H NMR, FTIR and elemental analysis. The structures of ligand and complex are measured via single crystal X-ray diffraction. The results of structural analysis of {[AgL]BF4}n indicated that each L as four-dentate ligand coordinate to the neighboring four-Ag(Ⅰ)centers, and each Ag(Ⅰ) is coordinated by four neighboring ligands L forming the quasi two-dimensional layerstructure. CCDC: 780087, L; 780086, complex.%本文以乙酰丙酮和对苯二甲醛进行缩合得到3,3′-(1,4-苯二甲稀基)-双-2,4-戊二酮配体(L),再同AgBF4进行配位反应,得到了{[AgL]BF4}n配位聚合物.分别采用1H NMR、FTIR和元素分析等对化合物进行了表征,并测定了配体和配合物的单晶结构.结构分析表明,在配位聚合物中,配体L作为四齿桥连配体分别与相邻的4个银(Ⅰ)配位,同时每1个银(Ⅰ)中心接受来自4个相邻配体的配位形成多孔的2D层状结构.
