Abstract：The synthesis and functional study of one-dimensional free radical-metal chain compound has been a hotspot task in molecule material, especially in composing high T_C molecule ferromagnet. A new compound [BrBzPy][Ni(dmit)₂] has been prepared and characterized. The crystal structure at room temperature was determined. The crystal is triclinic with space group P2₁/c，a=0.627 5(1) nm，b=1.743 8(3) nm，c=2.283 9(3) nm，α=90°，β=91.87(1)°，γ=90°，V=2.497(7) nm³，Z=4，Mr=700.57，and Dc=1.863 g·cm^-3. The planar [Ni(dmit)₂]^- is nearly perfect, which shows that it has good conjugate characteristic and is a 1-D magnetic chain compound.
