N2 - Methylenediisophthalic acid (H4MDIP), as semi-rigid 'V'-shaped carboxylate ligands, react with CoO, NiO and Cu(NO3) 2·3H2O to give three novel coordination polymers [H3O]2[Co3(MDIP)2]·2DMF (1), [Ni2(HMDIP)(μ2-OH)(H2O)3(DMF)] ·4H2O·DMF (2) and [Cu3(MDIP) (μ2-OH)2(H2O)4]·6.5H 2O (3) (DMF = N,N′-dimethylformamide). All compounds have been characterized by thermogravimetric analysis, IR spectroscopy, elemental and single-crystal X-ray diffraction analyses. Complex 1 is an unusual open anionic framework that is defined as the metal-organic replica of fluorite. Both 2 and 3 features a 3D open framework with one-dimensional elliptical channels and R- and L-helical chains, and their resulting frameworks can be rationalized as crb and pts topology respectively. An interesting feature of complex 3 is the presence of the linear Cu3 units that is formed by carboxylate and μ2-hydroxyl groups linking three Cu(II) metal centers. Magnetic investigations indicate that ferromagnetic couplings are dominant in the three compounds.
