摘要: Ni(ClO4)2·6H2O与香草醛和L-2-氨基-3-苯基-1-丙醇在三乙胺的存在下反应得到L-[Ni2(van)(Hvap)2(MeOH)2]ClO4·2.5MeOH·H2O (1)。通过元素分析、红外、热重分析和固体CD光谱对1的结构进行了表征,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=1,2个镍离子被脱去质子的香草醛分子桥联成{Ni2O}双核结构。固体CD光谱证实了1的手性。 |

Abstract: L-[Ni2(van)(Hvap)2(MeOH)2]ClO4·2.5MeOH·H2O (1) was prepared via the reaction of Ni(ClO4)2·H2O with o-vanillin and L-2-amino-3-phenyl-1-propanol in the presence of triethylamine. The structure of 1 was characterized by elemental analysis, IR, TGA, solid-state CD spectra and single-crystal X-ray diffraction analyses. The X-ray diffraction analyses reveal that the complex crystallizes in the monoclinic chiral space group P21 with Z=1. Two nickel (Ⅱ) ions are bridged by the deprotonated o-vanillin molecule, forming a {Ni2O} dinuclear structure. The solid-state CD spectra comfirm the chiral nature of 1. CCDC: 928211. |
Keywords: chiral polynuclear complex nickel(Ⅱ) complex crystal structure CD spectra |
