1D Mn(iii) coordination polymers exhibiting chiral symmetry breaking and weak ferromagnetism. Issue 16 (13th April 2021) - Hara, Aoi
Abstract : Weak ferromagnetism and chiral symmetry breaking of amide oxygen-bridged 1D Mn(iii ) coordination polymers are demonstrated. Abstract : Mn(iii ) complexes with achiral ligands, ( E )- N -(2-((2-aminobenzylidene)amino)-2-methylpropyl)-5-X -2-hydroxybenzamide (HL X, X = H, Cl, Br, and I), crystallise as chiral conglomerates containing amide oxygen-bridged one-dimensional coordination polymers that exhibit weak ferromagnetism. The bulk products exhibit symmetry breaking in that they do not contain equal amounts of enantiomers, though which is the dominant species depends on the substituent X.
