摘要
合成了3个具有不对称结构的Schiff碱配体H2Ln(n=1、2、3)。H2L1由乙酰丙酮、乙二胺和水杨醛缩合作用得到,H2L2由乙酰丙酮、(1R,2R)-环己二胺和水杨醛缩合作用得到,H2L3由苯甲酰丙酮、乙二胺和水杨醛缩合作用得到,每个反应中3个反应物的物质的量之比均为1∶1∶1。配体H2Ln分别与Ni(OAc)2.4H2O进行配位反应得到3个单核Ni(Ⅱ)配合物1,2和3。分别采用1H NMR、FTIR和元素分析对化合物进行了表征,并通过X-射线单晶衍射技术测定了3个配合物的晶体结构。
Three unsymmetrical Schiff base ligands H2Ln（n=1,2 and 3） have been synthesized.H2L1 was prepared by reaction from 1∶1∶1 condensation of 1,2-ethanediamine,acetylacetone and salicylaldehyde.H2L2 was prepared by reaction from 1∶1∶1 condensation of acetylacetone,（1R,2R）-diaminocyclohexane and salicylaldehyde.H2L3 was prepared by reaction from 1∶1∶1 condensation of benzoylacetone,1,2-ethanediamine and salicylaldehyde.Three mononuclear complexes 1,2 and 3 were prepared by reaction of three Schiff base ligands（H2Ln） with nickelous acetate respectively.The compounds were characterized by 1H NMR,FTIR,elemental analysis and X-ray diffraction single crystal structure analysis.CCDC： 825874,1;825875,2;825876,3.
