The title complex, C37H34N6NiO5, has been prepared and characterized by X-ray diffraction analysis. It crystallizes in the monoclinic system, space group P21/c with a = 1.15244(8), b = 1.69679(12), c = 1.78341(13) nm, β = 102.2320(10)°, V = 3.4082(4) nm3, Z = 4, Mr = 701.41, F(000) = 1464, Dc = 1.367 g/cm3 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 roles in the title complex’s thermostability.
