Study of the Crystal Structure of Oxo-bridged Binuclear FeⅢComplex with Chiral Salen Ligand

摘要

A oxo-bridged binuclear iron complex with chiral salen ligand[Fe2L2] O (H2L = R, R′-N, N′-bis(3, 5-di-tert-butylsalicy-laldene)-1, 2-cyclchexanediamine) has been synthesized and the structure has been determined by X-ray diffraction analysis. The title complex crystallizes in triclinic system with space group P-1. Crystal data: a = 1.42555(14) nm, b = 1.54889(15) nm, c=1.83662(17) nm, α=103.873(2)°, β=100.506(2)°, γ= 101.840(2)°, V= 3.7371 nm3, Dc= 1.082g/cm3 and Z = 2. In the complex, each iron center is pentacoordination and in distorted square-pyramidal environment.Two FeⅢ atoms are intramolecularly bridged by an oxygen atom with Fe…Fe nonbond distance of 0.3517(3) nm.
