title: Crystal structures and magnetic and ferroelectric properties of chiral layered metal-organic frameworks with dicyanamide as the bridging ligand.
abstract: Two homochiral 2D-layered frameworks composed of a Cu2O2 core and dicyanamide (dca) linkers, [Cu((R)-hmp*)(dca)]n (1) and [Cu((S)-hmp*)(dca)]n (2) (hmp*=alpha-methyl-2-pyridinemethanol), have been synthesized and structurally characterized. Preliminary investigations suggest that 1 and 2 show possible ferroelectric behaviors. Magnetic studies reveal the existence of strong antiferromagnetic interactions between the CuII centers in both complexes. The results demonstrate that 1 and 2 are multifunctional material candidates combining ferroelectric and antiferromagnetic properties in one molecule.
