| Abstract: | A novel dinuclear NiII complex, Ni2(ntc)(H2O)10]·7(H2O) (1), with 1,4,5,8-naphthaenetetracarboxylate (ntc) has been synthesized and characterized by X-ray diffraction analysis, IR, UV-vis spectra and thermogravimetric analysis. Complex 1 crystallizes in triclinic system, space group P-1, a = 7.721(3) Å, b = 9.458(3) Å, c = 11.453(4) Å, α = 114.110(6)°, β = 92.184(6)°, γ = 107.472(6)°, V = 715.7(4) Å3, Z = 1, final R = 0.048. Each nickel atom is octahedrally coordinated by five aqua ligands and one oxygen atom of the bridging ntc connecting two nickel atoms. The resulting dinuclear NiII complex forms a 3D H-bonded network. |
