| 摘要: 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。 |

| Abstract: Chiral Schiff-based ligand L-H2vap, derived from the condensation of o-vanillin and L-2-amino-3-phenyl-1-propanol, reacts with Cu(ClO4)2·6H2O, Gd(NO3)3·6H2O and triethylamine in the presence of 4-hydroxybenzoid acid to give L-[Cu4(Hvap)2(vap)2(MeOH)2](ClO4)2·2MeOH·H2O (1). The structure of 1 was characterized by EA, IR, TGA, solid-state CD spectra and the single-crystal X-ray diffraction analyses. The X-ray diffraction analyses reveal that the complex crystallize in the monoclinic system, chiral space group P21 with Z=2, containing a boat-shaped {Cu4O4} structure. Cu4 clusters in 1 are connected through intermolecular hydrogen bonding to form supramolecular chains along b axis. The solid-state CD spectra comfirm the chiral nature of 1. CCDC: 883888. |
