Synthesis and crystal structure of one-dimensional azide-bridged Mn(III) polymer [Mn(BrSal2MePn)(μ1,3-N3)] n (BrSaI2MePn = N,N′-bis(salicylidene)-1,2-propanediamine)

Abstract : A new one-dimensional manganese(III) Schiff base complex [Mn(BrSal2MeĐn)(μ1,3-N3)]n (I) was synthesized by the reaction of MnCl2 · 6H2O with the Schiff base ligand H2BrSal2MeĐn condensed from 2,2-dimethylpropylenediamine with 5-bromosalicylaldehyde and was characterized by elemental analyses and FT-IR spectroscopy. The molecular structure of I has been determined from single-crystal X-ray diffraction analysis. In this structure, the Mn3+ ion is in a distorted octahedral geometry with an obvious Jahn-Teller effect, where the deprotonated tetradentate Schiff-base ligand BrSal2MePn2− is bound in the equatorial plane and the N3− anions show μ1,3-bridging mode in the axial direction.
