Syntheses, structure and magnetic property of two metal-organic frameworks based on carboxylate-functionalized salen ligands

Two metal-organic frameworks 1 and 2 based on carboxylate-functionalized salen ligands were successfully obtained by one-step synthesis. 1 and 2 are isostructural, which display a porous framework constructed by infinite [CdNa2(H2O)2(DMF)(COO)4]n chains as nodes and [(ML)2Na(H2O)2] (M = Ni 1, Cu 2) units as linkers.239
