【摘要】：近年來(lái),配位化合物尤其是金屬有機(jī)框架化合物和金屬原子簇合物已成為配位化學(xué)領(lǐng)域的重點(diǎn)研究對(duì)象。金屬配合物越來(lái)越受到人們的關(guān)注,這歸因于它們有趣的拓?fù)浣Y(jié)構(gòu)和廣泛的應(yīng)用,如選擇性分離、催化、氣體存儲(chǔ)、生物醫(yī)學(xué)成像和非線性光學(xué)等。配位化合物的性質(zhì)主要由其結(jié)構(gòu)決定,所以配體的選擇和金屬的配位構(gòu)型是廣大研究者需要重點(diǎn)考慮的問(wèn)題。本文利用溶劑熱合成法成功構(gòu)筑了7例配位化合物,系統(tǒng)探究了它們的配位模式和拓?fù)浣Y(jié)構(gòu),并選取部分配合物進(jìn)行光學(xué)和磁性研究,本論文的主要研究結(jié)果為:1、利用原位反應(yīng)得到的雙二齒配體2-嘧啶甲酸(L)與六配位的過(guò)渡金屬M(fèi)n(Ⅱ)組裝,采用溶劑熱的方法合成出兩個(gè)新型過(guò)渡金屬配合物。二維63層狀配合物[MnCl(L)H2O]n(1)中,兩種六邊形的Mn環(huán)是由MnII離子和L配體以及雙氯離子相互連接形成的。然后,使用甲酸代替配合物1中的部分氯離子可得到包含二重互穿srs-型網(wǎng)絡(luò)結(jié)構(gòu)的[Mn2Cl1.5L2(HCO2)0.5]n(2)。在srs-型網(wǎng)絡(luò)中,L配體橋接MnII離子可得到一個(gè)一維鏈,而進(jìn)一步連接雙氯離子和Cl/甲酸便形成了二重互穿的srs-型網(wǎng)絡(luò)結(jié)構(gòu)。非線性光學(xué)測(cè)試結(jié)果表明,化合物2展現(xiàn)了明顯的二階倍頻信號(hào),響應(yīng)強(qiáng)度大約是KH2PO4(KDP)的0.8倍。2、以8-羥基喹啉為有機(jī)配體,采用溶劑熱的方法合成了5個(gè)新型3d-4f金屬簇合物,并對(duì)它們進(jìn)行了單晶X射線衍射表征。然后,我們對(duì)配合物6進(jìn)行了催化活性的探索,該配合物可以催化2-呋喃甲醛與嗎啉作用生成(4S,5R)-雙嗎啉代環(huán)戊-2-烯酮的反應(yīng);對(duì)配合物7進(jìn)行了磁性的研究,表明Er4Ni9簇合物是鐵磁的。
[Abstract]:In recent years, coordination compounds, especially organometallic framework compounds and metal cluster compounds, have become the focus of research in the field of coordination chemistry. This is due to their interesting topology and extensive applications, such as selective separation, catalysis, gas storage, biomedical imaging and nonlinear optics. Therefore, the selection of ligands and the coordination configuration of metals are important issues to be considered by many researchers. In this paper, seven coordination compounds were successfully constructed by solvothermal synthesis, and their coordination patterns and topological structures were systematically investigated. Some of the complexes were selected for optical and magnetic studies. The main results of this thesis were: 1: 1. The binodentate ligand 2-pyrimidine formate L-) was assembled with hexagonal transition metal Mn( 鈪，
