Study of the crystal structure of oxo-bridged binuclear Fe-III complex with chiral salen ligand

A oxo-bridged binuclear iron complex with chiral salen ligand [Fe2L2]O (H2L = R, R'-N, N'-bis(3, 5-di-tert-butylsalicylaldene)-1, 2-cyclohexanediamine ) has been synthesized and the structure has been determined by X-ray diffr action analysis. The title complex crystallizes in triclinic system with sp ace group P-1. Crystal data: a=1.42555 (14) nm, b=1.54889 (15) nm, c=1.8366 2 (17) nm, alpha =103.873 (2)degrees, beta =100.506 (2)degrees, gamma =101. 840 (2)degrees, V= 3.7371 nm(3), D-c=1.082 g/cm(3) and Z=2. In the complex, each iron center is pentacoordination and in distorted square-pyramidal en vironment. Two Fe-III atoms are intramolecularly bridged by an oxygen atom with Fe . . . Fe nonbond distance of 0.3517 (3) nm.
