摘要 合成了标题化合物[Co2(bte)3(NCS)4(H2O)2]n(bte=1,2-双(三氮唑-1-基)乙烷),用X射线单晶衍射仪测定了晶体结构,空间群为P墿,a=7.7962(2),b=8.3407(4),c=14.7735(5),α=86.835(2),β=76.2031(9),γ=80.583(3)°.晶体包含两个独立的结构[Co(bte)(NCS)2(H2O)2]和[Co(bte)2(NCS)2].[Co(bte)(NCS)2(H2O)2]的结构是由1个bte配体桥联2个Co2+离子形成的一维中性链,其中Co2+离子位于由bte的4个氮原子和2个反式NCS-的2个氮原子和2个水分子组成的扭曲八面体环境中.[Co(bte)2(NCS)2]的结构是由2个bte配体桥联2个Co2+离子形成的一维中性链,其中Co2+离子位于由bte的4个氮原子和两个反式NCS-的2个氮原子组成的扭曲八面体环境中. The title complex [Co2 （bte） 3 （NCS） 4 （ H2O） 2]n （ bte = 1,2-bis （triazol-l-yl） ethane） has been prepared and characterized. Single-crystal X-ray analysis reveals that the complex crystallizes in space group Pi with a= 7. 796 2（2）, b= 8.340 7（4）, c=14.773 5（5） A, α=86.835（2）, β=76.203 1（9）, γ=80.583（3）°. The crystal consists of two discrete complexes,[Co（bte）2 （NCS）2] and [Co（bte） （NCS）2 （H2O）2 ]. The structure of [Co（bte）2 （NCS）2] demonstrates a one- dimensional neutral chain through bte-bridge, in which the Co（Ⅱ） atom is in a distorted octahedral environment formed by four nitrogen atoms of the triazoles and two nitrogen atoms from two trans thiocyanato liagnds. The structure of [Co（bte） （NCS）2（H2O）2] consists of neutral chain containing Co（Ⅱ） bridged by bte molecules. The six-co-ordination of Co^2＋ is achieved by means of two trans NCS ions and water molecules. The IR spectra have also been investigated.
