A complex [Ni(α-furacrylic acid)2(4,4′-bipy)(H 2O)5]n with α-furacrylic acid, 4,4′-bipy and Nickel perchlorate has been synthesized by means of hydrothermal way and characterized. Crystal data for this complex: monoclinic, space group P21/c, a = 1.1222(2) nm, b = 1.084 1(2) nm, c = 1.081 6(2) nm, β=98.37(3)°, V=1.301 8(5) nm3, Dc= 1.524 g·cm-3, Z=2, μ(Mo Kα)=0.813 mm-1, F(000)=624, S=1.073, R1=0.041 2, wR2=0.093 4. The crystal structure shows that the Nickel(II) ion is coordinated with two nitrogen atoms of two 4,4′-bipy molecules and...
