Solvent-dependent assemblies, structure diversities and magnetic properties of two homochiral Co(ii)/Na(i) coordination polymers

Abstract

Solvent-induced synthesis of 2D and 3D homochiral Co(II)/Na(I) coordination polymers based on chiral tridentate ligand S-N-(1-hydroxymethylethyl)iminodiacetic acid (S-H₃L), formulated as [NaCo(S-L)(μ-H₂O)(H₂O)] (S-1) and [NaCo(S-L)(H₂O)] (S-2). Compound S-1 displays a 2D layered structure, i.e. further expanded into a 3D supramolecular architecture by hydrogen bond interactions, whereas S-2 features a 3D framework constructed by 1D Co(II) and Na(I) chains. In addition, magnetic study reveals the anti-ferromagnetic interaction in S-2.
