A copper(II) coordination polymer, bis(isonicotinato)copper(II) dihydrate, was prepared using a hydro(solvo)thermal process and characterized by a single-crystal X-ray diffraction method and elemental analysis. Crystal data: [Cu(II)(C6H4O2N)2·2H 2O]n, monoclinic, Cc, Z = 4, a = 4.9967(5)Å, b = 24.971(2) Å, c = 11.110(1) Å,β = 98.86(1)°, V = 1368.5(2)Å3, R1 = 0.023, and wR2 = 0.058. The structure is a three-dimensional metal-organic coordination network containing diamond-shaped tunnels. Magnetic studies show that the magnetic susceptibility data in the temperature range 2.0-300 K can be fitted to a Curie - Weiss law with θ = - 0.93 K and C = 0.398 emu K/mol (s = 1/2, g = 2.06), which corresponds to an effective magnetic moment (μeff) per copper ion of 1.78 BM. The magnetism result indicates that there is no strong interaction between copper centers within the network structure.
