Synthesis, X-Ray Structural Characterization, And Catalytic Property Of An End-To-End Azido-Bridged Polymeric Manganese(Iii) Complex Derived From N,N '-Bis(5-Fluorosalicylidene)-1,2-Diaminoethane

A new end-to-end azido-bridged polymeric manganese(III) complex [MnL(mu(1,3)-N-3)](n) with the Schiff base ligand N, N'-bis(5-fluorosalicylidene)-1,2-diaminoethane (H2L), has been synthesized and structurally characterized by physicochemical methods and single-crystal X-ray determination. Crystal of the complex crystallizes in orthorhombic space group Pca2(1), with a = 10.8211(5), b = 13.4644(6), c = 11.1811(5) angstrom =1629.08(13) angstrom, Z = 4, R-1 = 0.0255, wR(2) = 0.0653, GOOF = 1.053. X-ray analysis indicates that the complex is an end-to-end azido-bridged polymeric manganese species. The Mn atom is coordinated in an octahedral coordination by two phenolate O and two imine N atoms from the Schiff base ligand, and two azido N atoms. The catalytic property for epoxidation of styrene by the complex was evaluated.
