香草醛和L-2-氨基-3-苯基-1-丙醇缩合得到的手性希夫碱配体(L-H2vap)与Cu(ClO4)2.6H2O,Gd(NO3)3.6H2O和三乙胺在4-羟基苯甲酸的存在下反应得到L-[Cu4(Hvap)2(vap)2(MeOH)2](ClO4)2.2MeOH.H2O(1)。通过元素分析、红外、热重分析和固体CD光谱对1结构进行了表征,并通过X-射线单晶衍射确定其单晶结构,结果表明1属于单斜晶系,P21手性空间群,Z=2,包含船型{Cu4O4}结构。1的Cu4簇通过配体、溶剂分子和高氯酸根离子的氧原子间的氢键沿b轴形成超分子链。固体CD光谱证实了1的手性。
(L-H2vap) with Cu (ClO4) 2.6H2O, Gd (NO3) 3.6H2O and triethylenetetramine The amine is reacted in the presence of 4-hydroxybenzoic acid to give L [Cu4 (Hvap) 2 (vap) 2 (MeOH) 2] (ClO4) 2.2MeOH.H2O (1). The structure of 1 was characterized by elemental analysis, IR, TG and CD spectra. The single crystal structure was confirmed by X-ray single crystal diffraction. The results showed that 1 belongs to monoclinic system, P21 chiral space group, Z = 2, including the ship {Cu4O4} structure. 1 Cu4 cluster forms a supramolecular chain along the b axis through the hydrogen bond between the ligand, the solvent molecule and the oxygen atom of the perchlorate ion. Solid CD spectra confirmed the chirality of 1.
