Treatment of bis(2-dimethylaminoethyl) ether (BDMAE) with nickel acetate affor- ded a novel 3D nickel(II) complex [Ni(BDMAE)(H2O)3•(CH3COO)2•(H2O)2] under solvothermal conditions. Its crystal structure was characterized by elemental analysis, IR spectrum, PXRD and single-crystal X-ray diffraction analysis. The complex belongs to the orthorhombic system, space group C2221 with a = 8.823(2), b = 13.932(3), c = 17.563(4) Å, V = 2158.9(8) Å3, Z = 4, C12H36N2NiO10, Mr = 427.14, Dc = 1.314 g/cm3, F(000) = 920 and μ = 0.944 mm-1. Single-crystal X-ray diffraction reveals that the mononuclear nickel(Ⅱ) ion is six-coordinated to one oxygen, two nitrogen atoms of the BDMAE ligand and three oxygen atoms of coordinated water molecules. The complex exhibits a 3D supramolecular structure through a variety of intermolecular and intramolecular hydrogen bonding interactions. In addition, the complex has been investigated for catalytic properties towards the Henry reaction of nitromethane with p-nitrobenzaldehyde, and the results indicated that the 1-p-nitrophenyl-2-nitroethanol product was obtained in excellent yield under optimum conditions with the complex as the catalyst.
