Preparation and Structure of Nickel Complex Ni(dppe)Cl2

Abstract

Mononuclear nickel complex Ni(dppe)Cl₂ (dppe = Ph₂PCH₂CH₂PPh₂) was prepared by reaction of NiCl₂·6H₂O and dppe in CH₂Cl₂/methanol solution and its structure was determined by single crystal X-ray diffraction analysis. The crystals are monoclinic, space group P2₁/c with a = 12.228(3), b = 15.235(4), c = 15.294(4) Å, a = 90.00, b = 105.933(4), g = 90.00°, V = 2739.7(13) ų, Z = 4, F₍₀₀₀₎ = 1256, D_c = 1.486 g/cm³, μ = 1.231 cm^-1, the final R = 0.0543 and wR = 0.1297. A total of 28157 reflections were collected, of which 6516 were independent (R_int = 0.0620).
