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

Abstract

ABSTRACTA new end-to-end azido-bridged polymeric manganese(III) complex [MnL(μ1,3-N3)]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 Pca21, with a = 10.8211(5), b = 13.4644(6), c = 11.1811(5) Å, V = 1629.08(13) Å3, Z = 4, R1 = 0.0255, wR2 = 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.
