摘要
Three novel MnIII polymers, [Mn(phox)2(N 3)]n (1), [Mn(Etphox)2(N3)] n (2), and [Mn(Etphox)2(C2N3)] n (3), using achiral ligand Hphox (Hphox = 2-(4,5-dihydrooxazol-2-yl) phenol) and chiral ligand HEtphox (HEtphox = 2-(4-ethyl-4,5-dihydrooxazol-2-yl) phenol) were synthesized and structurally and magnetically characterized. All complexes are of 1D chain structures and form 2D frameworks by weak interactions. The adjacent 1D chains of complex 1 are connected by face-to-face π-π interactions, C-H⋯π interactions, and hydrogen bonding, which leads to the formation of a supramolecular 2D sheet structure. The three compounds show antiferromagnetic coupling between MnIII ions. And compound 2 is a spin-canted weak ferromagnet with TN = 5.6 K, showing metamagnetic behavior with a two-step magnetic phase transition.
