Abstract: [Ni(H2O)6][H2N(C2H4)2NH2](SO4)2 is an inorganic-organic compound with a new open framework synthesized by hydrothermal method, and characterized by means of single-crystal diffraction and spectroscopic data. The compound crystallized in a monoclinic space group P21/n with a=1.29089(2) nm, b=1.06301(3) nm, c=1.33202(4) nm, β=114.0870(10)°, V=1.67127(8) nm3, Z=4, and was solved by using the direct method and the least-squares refinement converged at R=0.0214[I>2σ(I)]. The structure consists of isolated Ni(H2O)6 octahedra and SO4 tetrahedra, with both of them hydrogen-bonded to piperazine cations.
