Abstract | Rational design of magnetic materials with desired magnetic properties has attracted wide interest in recent decades. Herein, we present a new 2D cobalt(II) metal-organic framework, namely [Co(MQ)2(V2O6)2]n·4nH2O 1, which was hydrothermally synthesized by the reaction of Co(NO3)2·4H2O, N-methyl-4,4′-bipyridinium(MQ+) chlorine salt and NH4VO3. Single-crystal X-ray diffraction analysis reveals that 1 crystallizes in C2/c space group with a = 16.290(5), b = 7.815(2), c = 25.297(7) ?, β = 108.459(5)°, V = 3054.8(15) ?3, Z = 4, Dc = 1.890 g/cm3, μ = 1.791 mm-1, F(000) = 1748, the final R = 0.0444 and wR = 0.1208 with I > 2σ(I). The individual Co(II) is connected and well separated by diamagnetic [V2O6]2-linkers. Magnetic measurements confirm that 1 exhibits ferrimagnetic interactions |
