摘要

Hydrothermal reactions of NiSO4 and 1-hydroxyethylidenediphosphonic acid (hedpH4) in the presence of different organic templates resulted in the formation of three new compounds: (enH2)Ni(hedpH2)2·2H 2O 1, (pnH2)Ni(hedpH2)2(H2O), 2 and (bnH2)Ni(hedpH2)2-(H2O)2, 3, (hedp = 1-hydroxyethylidenediphosphonate, en = ethylenediamine, pn = 1,3-propanediamine, bn = 1,4-butylenediamine). Crystal data: 1, monoclinic, C2/c, a = 24.7864(5), b = 5.2565(1), c = 16.0468(2) Å, β= 117.903(1)°, V = 1847.67(6) Å3, Z = 4; 2, triclinic, P1, a = 10.0926(4), b = 10.5621(4), c = 10.9212(4) Å, α = 111.520(1), β= 110.833-(1), γ = 93.630(1)°, V = 986.77(7) Å3, Z = 2; 3, monoclinic, C2/c, a = 16.230(2), b = 12.430-(13), c = 12.657(13) Å, β= 121.997(10)°, V = 2165(4) Å3, Z = 4. The compound 1 has a one-dimensional chain structure which is composed of corner-sharing {NiO6} octahedra and {O3PC} tetrahedra with the ethylenediammonium cations and water molecules stabilized between the chains. By replacing ethylenediamine with 1,3-propanediamine or 1,4-butylenediamine, molecular species have been obtained. The compound 2 contains dimers of [Ni(hedpH2)2(H2O)]22- whereas 3 is a mononuclear compound. The thermal stabilities, spectroscopic and magnetic properties of all three compounds have been investigated.
