摘要
研究了18-冠-6与Na2[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[{Na(18-C-6)}2(H2O)][Ni(i-mnt)2](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=1.0991(12)nm,b=1.1011(12)nm,c=1.1305(12)nm,α=70.44(2)°,β=87.44(2)°,γ=62.552(19)°,V=1.134(2)nm3,Z=1,F(000)=488,R1=0.3771,wR2=0.1497。(1)中的[Ni(i-mnt)2]基团通过配体i-mnt的氮原子与两个[Na(18-C-6)]基团之中的钠原子成键,形成稳定的中性配合物。
The 18-crown-6 (18-C-6) reacts with Na2 [Ni (i-mnt)3] {i-mnt = iso-1, 2dicyanoethene-1, 2-dithiolate,[S2C2(CN)2]2-},and forms a complex [{Na(18-C-6)}2(H2O)][Ni(i-mnt)2],which was characterized by elemental analysis. The complex belongs to triclinic, space group P-1 with cell dimensions:a=1. 0991 (12)nm,b= 1. 1011 (12)nm,c=1.1305(12)nm,α=70. 44(2)°,β=87. 44 ( 2)°,γ= 62. 552(19)°,V=1. 134(2)nm3,Z=1,F(000) = 488,R1 = 0. 3771,wR2= 0. 1497. The complex is composed of two[Na(18-C-6)] complex cations and one [Ni (i-mnt)2] complex anion combined through Na-N binding.
