摘　　要：研究了18-冠-6分别与Na2[M(mnt)2][M=Cu,Ni;mnt=丁二腈烯二硫醇阴离子,C2S2(CN)22-]的反应,得到的配合物{[Na(18-C-6)][Na(18-C-6)(H2O)]}[Cu(mnt)2](1),[Na(18-C-6)(H2O)]2[Ni(mnt)2]@(18-C-6)(2)通过元素分析、红外光谱、X射线单晶衍射进行了表征.两个配合物均为三斜晶系,空间群P1.1的晶体学结构数据:a=1.22697(19)nm,b=1.22780(19)nm,c=1.5665(3)nm,α=95.083(3)°,β=101.534(3)°,y=91.007(3)°,V=2.3016(6)nm3,Z=2,Dcalcd=1.350g/cm3,F(000)=976,R1=0.0726,wR2=0.1843.2的晶体学结构数据:a=1.11620(17)nm,b=1.22054(18)nm,c=1.27939(18)nm,α=111.647(2)°,β=92.792(3)°,y=103.201(2)°,V=2.5461(4)nm3,Z=1,Dcalcd=1.304g/~cm3,F(000)=642,R1=0.0459,wR2=0.1003.1中的[Cu(mnt)2]2-通过mnt的氮原子与[Na(18-C-6)]+中的钠原子成键,形成了一维链状结构;[Na(18-C-6)(H2O)]+只起平衡电荷的作用.2中的[Ni(mnt)2]2-也通过配体的mnt氮原子与两个[Na(18-C-6)(H2O)]+中的钠原子成键,形成稳定的中性配合物.Reactions of 18-crown-6 (18-C-6) with Na-2[M(mnt)(2)] [M = Cu, Ni; mnt = 1,2-dicyanoedhene-1,2-dithiolate, C2S2 (CN)(2)(2-)] were studied and the novel complexes ([Na(18-C-6)] [Na(18-C-6)-(H2O)])-[Cu(mnt)(2)] (1) and [Na(18-C-6) (H2O)](2)[Ni(Mnt)(2)] . (18-C-6) (2) were characterized by elemental analysis, IR and X-ray diffraction analysis. I and 2 belong to triclinic, space group P (1) over bar widi cell dimensions: 1, a = 1.22697(19) nm, b = 1.22780 (19) mn, c = 1.5665 (3) mn, alpha = 95.083 (3)degrees, beta = 101.534(3)degrees, gamma = 91.007(3)degrees, V = 2.3016(6) nm(3), Z = 2, D-calcd = 1. 350 g/cm(3), F(000) = 976, R-1 = 0.0726, wR(2) = 0.1843 and 2, a = 1.11620(17) mn, b 1.22054 (18) mn, c = 1.27939 (18) nm, a = 111.647 (2)degrees, beta = 92.792(3)degrees, gamma = 103.201 (2)degrees, V = 2.5461 (4) nm(3), Z = 1, D-calcd = 1.304 g/cm(3), F(000) = 642, R-1 = 0.0459, wR(2) = 0.1003. 1 Displays a one - dimensional chain of [Na(18-C-6)](+) Complex cations and [Cu(mnt)(2)](2-) complex anion bridged by Na - N interactions. The complex cation [Na(18-C-6)(H2O)](+) serves as a balancing charge in crystal. In 2, two [Na(18-C-6)(H2O)](+) complex cations and a [Ni(mnt)(2)](2) - complex anion form a stable neutral complex through Na - N binding.
