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)]center dot 2H(2)O (1), [Ni-2(mal)(2)(bpy)]center dot 2H(2)O (2), [Ni-2(mal)(2)-(bpe)]center dot 3H(2)O (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)(2)L] and [M-2(mal)(2)L], 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. (C) 2012 Elsevier B. V. All rights reserved.
