研究了15-冠-5与K2[Ni(i-mnt)2]{i-mnt=异丁二腈烯二硫醇阴离子,[S2C2(CN)2]2-}的反应,得到的配合物[K(15-C-5)2]2[Ni(i-mnt)2]·2H2O(1)通过元素分析、红外光谱、X射线单晶衍射进行了结构分析。配合物为三斜晶系,空间群P-1。晶体学结构数据:a=1.2674(5)nm,b=1.6317(7)nm,c=1.7771(7)nm,α=102.397(7)°,β=104.828(8)°,γ=93.659(7)°,V=3.442(2)nm3Z=2,F(000)=1412,R1=0.0727,wR2=0.1283。(1)中的[Ni(i-mnt)2]基团通过配体i-mnt的氮原子与两个[K(15-C-5)2]基团之中的钾原子成键,形成稳定的中性配合物。
The reaction of 15-crown-5 （15-C-5） with K2[Ni（i-mnt）2]{i-mnt= iso-1, 2dicyanoethene-1, 2-dithiolate, [S2C2（CN）2]^2-} was studied and the complex [K（15-C-5）2]2 [Ni（i-mnt）2]·2H2O was characterized by elemental analysis, IR spectrum and XRD. The complex belongs to triclinic, space group P-1 with cell dimensions： a=l.2674（5）nm, b=1.6317（7）nm, c=1.7771（7）nm, a=102.397（7）°, β=104.828（8）°, γ=93.659（7）°, V=3.442（2）nm^3 Z=2, F（000）=1412, R1=0.0727, ωR2=0.1283. The complex is composed of two [K（15-C-5）2]^＋ cations and one [Ni（i-mnt）2]^2- anion, and forms a stable neutral comnlex through K-N binding.
