Synthesis, structural analysis and magnetic property of a chiral Mn(II) coordination polymer

► Revealing novel chiral 2-D rectangular-grid layers survived up to 200 °C with a cavity dimension of 11.658 × 5.273 Å2). ► Lattice water chains hydrogen-bonding to the chiral 2-D rectangular-grid layers to for a 3-D supramolecular network. ► Existing weak antiferromagnetic interactions between the Mn(II) centers.
