Synthesis and Characterization of Nickel（Ⅱ） Complex Bearing 2,9- di-tert-butyl-1,10-phenanthroline Ligand

The complex DtbpNiCl2(Dtbp = 2,9-di-tert-butyl-1,10-phenanthroline) was synthe- sized and characterized by X-ray single-crystal structure analysis. For the complex: C20 H24 Cl2 N2 Ni CH2 Cl2, Mr = 506.95, monoclinic, space group P21 /c, a = 9.5905(3), b = 13.7587(3), c = 17.3364(5), β = 94.244(2)°, V = 2281.31(11)3, Z = 4, Dc = 1.476 g/cm3, λ = 1.54184, μ = 5.606 mm-1, F(000) = 1048, S = 1.079, R = 0.0402 and wR = 0.1010 for 3223 observed reflections with I 2σ(I). In complex DtbpNiCl2, the nickel adopts a distorted tetrahedral geometry coordinated by two nitrogen atoms of Dtbp and two chlorine ions. The complex is connected by intermolecular C–H···Cl hydrogen bonds to form a 1D structure in the solid state.
