Three new homochiral metal-organic frameworks (MOFs) based on malate anions and N-donor linkers of different length have been prepared. [Co 2(mal) 2(bpy)]·2H 2O (1), [Ni 2(mal) 2(bpy)]·2H 2O (2), [Ni 2(mal) 2(bpe)]·3H 2O (3) (mal = S-malate, bpy = 4,4′-bipyridyl, bpe = trans-1,2-bis(4-pyridyl)ethylene) were characterized by a number of analytical methods including single crystal X-ray analysis. Optical purity of compounds 2 and 3 was confirmed by polarimetry experiments. Compounds 1 and 2 contribute to the family of isoreticular M(II) malates and aspartates ([M 2(asp) 2L] and [M 2(mal) 2L], M = Cu, Co, Ni; L = ditopic rigid organic ligand) where all structural units (metal cations, chiral ligands and bridging ligands) could be changed with retention of the topology in the resulting framework. Compound 3 has a different structure and contributes to a different family of isoreticular homochiral MOFs.
