Under given conditions, two complexes of [Ni(H2O)2BEDA]·2H2O 1 and [Ni(Py)2-BEDA]·6H2O 2 (BEDA = bis(3-methoxy-2-pyridyl)ether-6,6′-dicarboxylic acid) have been synthe-sized and characterized by elemental analysis and X-ray single-crystal diffraction. Crystal data for 1: C14H18NiN2O11, monoclinic C2/c, a = 14.3844(17), b = 12.9900(15), c = 9.6309(11), β = 104.3350(10)°, V = 1743.5(4)3, Z = 4, Dc = 1.711 g/cm3, F(000) = 928, μ = 1.179 mm-1, Mr = 449.01, the final R = 0.0228 and wR = 0.0625. Crystal data for 2: C24H32NiN4O13, triclinic P1, a = 9.423(2), b = 11.863(3), c = 13.089(3), α = 91.511(3), β = 92.465(3), γ = 100.696(2)°, V = 1435.6(6)3, Z = 2, Dc = 1.488 g/cm3, F(000) = 672, μ = 0.748 mm-1, Mr = 643.25, the final R = 0.0400 and wR = 0.0975. Interestingly, in the two complexes, lattice water molecules dominate its crystal structures. Therefore, extensive intermolecular hydrogen bonds assemble 1 and 2 into 2D extended sheets and a 3D open framework, respectively. Furthermore, water molecules present in 2 are associated to form water clusters.
