用中心离子替代和空气自动氧化的方法由(Bu_4N)_2[Zn(dmit)_2]一步合成了 (Bu_4N)[Ni(dmit)_2]，这种方法可推广到其它Z[M(dmit)_2]配合物和Z[M(dmit) _2]_2导电配合物的合成(Bu_4N)[Ni(dmit)_2]结晶过程中出现两个晶相，其中空间 群为C2/c的侧心单斜相为新晶相，X射线结构测定结果为：a=2.0191(2)nm, b=1. 3404(1) nm,β=105.55(1)~°,V=3165.5(6)nm~3, R=0.055,　晶体中的Ni(dmit) _2]－呈D_(2h)点群对称性，平面性接近完美，共轭性相当显著，相邻Ni(dmit)_2] －平面间的夹角为75.56（3）~°。

(Bu_4N)[Ni(dmit)2] was synthesized by substituting Zn2+ in (Bu_4N) _2[Zn(dmit)_2] with Ni2+ and by auto-oxidation in acetone solution. This simple method can be extended to synthesize other Z [ M ( dmit )2 ] type complexes and Z[M(dmit)2]2 type conductive complexes. Two crystalline phases of (Bu_4N) [Ni(dmit)_2] , namely triclinic P1-bar phase and monoclinic C2/c phase which has been proved new, were obtained. The crystalline data of the C2/c phase are: a =2.0191(2) nm, 6 = 1.3404(1) nm, c = 1.2141(1) nm, β= 105.554(8)°, F=3165.5(6) nm3, R =0.055, C2/c space group.
