The title complex Co(bzacen) (bzacen=N,N'-dibenzoylactoneethylenediamine) was prepared and characterized by X-ray diffraction analysis and elemental analysis.In the solid state,the cobalt complex crystallized in monoclinic system,with space group P2₁/c,a=1.7297(9) nm,b=0.7148(4) nm,c=2.1099(12) nm,β=110.752(2)°,V=1.83807(13) nm³,D_x=1.465 Mg/m³,Z=4,μ=0.090 mm^-1, F(000)=844,S=1.01.The structure was refined to R₁=0.030 and wR₂=0.074 for the observed 3103 reflections with I>2σ(I).The Co atom lies in a slightly distorted square-planar geometry composed of two coordinating nitrogen atoms and two coordinating oxygen atoms.The complex was investigated as precursor for butadiene polymerization,and it showed high activity and high cis-1,4 selectivity when activated by cocatalyst Al₂Et₂Cl₃ or AlEt₂Cl.
