本文报道了2个手性Salen型过渡金属配合物[(N,N'-bis(3-t-butyl-5-methylsalicylidene)-1S,2S-cyclohexanediamine-N,N',O,O')nickel(Ⅱ)](1)和[N,N'-bis(3-t-butyl-5-methylsalicylidene)-1S,2S-cyclohexanediamine-N,N',D,O')copper(Ⅱ)](2)的合成、波谱与结构表征.它们由(1S,2S)-环己烷-1,2-二胺和3-叔丁基-5-甲基-2-羟基苯甲醛发生席夫碱缩合反应制得的配体分别与Cu(Ⅱ)和Ni(Ⅱ)盐反应而得到.产品经过红外光谱、元素分析、电喷雾质谱、紫外和圆二色光谱等方法表征,并测定其晶体结构.结果表明配合物1和2中的中心金属离子Cu(Ⅱ)和Ni(Ⅱ)均为四配位平面正方形配位构型,而且在其晶体堆积中观察到一种通过芳环之间弱π-π相互作用形成的二聚结构.

Two chiral Salen-type transition-metal complexes, named as (N,N'-bis(3-t-butyl-5-methylsalicylidene)-1S, 2S-cyclohexanediamine-N,N',O,O') nickel(Ⅱ) (1) and (N,N'-bis(3-t-butyl-5-methylsalicylidene)-1S,2S-cyclohexa-nediamine-N,N',O,O') copper(Ⅱ) (2), were obtained from the Schiff base condensation between (1S,2S)-cyclohexane-1,2-diamine and 3-tert-butyl-5-methyl-2-hydroxybenzaldehyde. X-ray diffraction crystal structural analyses of 1 and 2 demonstrate that they are isostructural and each central metal ion (M (Ⅱ)) presents square-planar coordination configuration. Both of them are fully characterized by mass spectrometry, FFIR, elemental analysis, UV-Vis spectra and circular dichroism (CD) spectra. A dimeric packing mode via weak offset π-π stacking is observed in the crystal packing structures of 1 and 2. CCDC: 685302, 1; 685303, 2.
