合成了一个新颖的离子对化合物[TBA][Ni(dddt)2](1)(TBA=tetra-N-butylammonium,dddt2-=5,6-dihydro-1,4-dithiin-2,3-dithiolate),单晶衍射结果表明化合物1属于单斜晶系,空间群为P21/c,晶体不对称单元含1个[Ni(dddt)2]-阴离子以及1个[TBA]+阳离子.在[Ni(dddt)2]-阴离子中,Ni离子呈现平面正方形配位几何构型,相邻阴离子间存在弱的S…S相互作用.在化合物1晶体中,阴、阳离子间弱的堆积作用以及静电作用将化合物1连接形成三维分子固体.
A novel ion pair compound [TBA] [Ni (dddt) 2] (TBA = tetra-N-butylammonium, dddt2- = 5,6-dihydro- 1,4-dithiin-2,3-dithiolate ). The results of single crystal diffraction show that compound 1 belongs to the monoclinic system with space group P21 / c and the crystal asymmetric unit contains 1 [Ni (dddt) 2] - anion and 1 [TBA] + cation. (dddt) 2] - anions, Ni ions exhibit planar square coordination geometry and weak S ... S interaction exists between adjacent anions. In Compound 1 crystal, the weak accumulation between anion and cation and the electrostatic interaction Compound 1 is connected to form a three-dimensional molecular solid.
