The title complex, C37H34N6NiO5, has been prepared and characterized by X-ray diffraction analysis. It crystallizes in the monoclinic system, space group P2（1/c） with a = 1.15244（8）, b = 1.69679（12）, c = 1.78341 （13） nm, β = 102.2320（10）°, V = 3.4082（4） nm^3, Z = 4, Mr = 701.41, F（000） = 1464, Dc = 1.367 g/cm^3 and μ（MoKα） = 0.622 mm^-1. The structure was refined to R = 0.0459 and wR = 0.1199 for 5718 observed reflections. The intramolecular hydrogen bonds in the crystal structure play important rol...
