One-dimensional Chain Crown Ether Complexes. Synthesis and Crystal Structure of 18-Crown-6 Complex:[Na(18-Crown-6)]2[Zn(mnt)2]
【摘要】 研究了18冠6与Na2[Zn(mnt)2]的反应,并通过元素分析、红外光谱、单晶X-射线衍射对生成的配合物[Na(18-C-6)」2[Zn(mnt)2]进行了表征.配合物为单斜晶系,空间群C2/c.晶体学数据:α=2.241(6),b=1.135 9(3),c=1.988 7(6)nm,β=120.391(4)°,V=4.368(2)nm3,Z=4,Dcalcd=1.399g/cm3,F(000)=1920,R1=0.036 2,wR2=0.056 0.在固态,配合物中,两个分子通过18冠6氧原子连接形成一维链状结构.
【Abstract】 The novel complex [Na(18-C-6)]2[Zn(mnt)2](1)was characterized by elemental analysis,IR spectrum and X-ray diffraction analysis. 1 beolngs to monoclinic, space group C2/c with cell dimensions: a = 2. 241 8 (6),6=1. 135 9(3),c = 1. 988 7(6) nm,β=120. 391(4),V=4. 368(2) nm3,Z=4,Dcalcd=1. 399 g/cm3,F(000) = 1 920,wR1 = 0. 036 2,wR2 = 0. 056 0. The complex display an one-dimensional chain of [Na(18-C-6)]+complex cations and[Zn(mnt)2]2- complex anion bridged by Na-O interactions between adjacent[Na(18-C-6)]+units.
