Synthesis and crystallographic structure of nickel(0) carbonyl complex with Bitianp, an atropoisomeric diphosphine Fusè, Marco Facchetti, Giorgio Rimoldi, Isabella Castellano, Carlo Carbonyl Sigma donor Envelope ring Nickel complex Tetrahedral geometry Atropoisomeric diphosphine The reaction between an atropoisomeric diphosphine, Bitianp and [Ni(CO)4] was achieved by direct condensation in CH3Cl to afford complexes of general formula [Ni(CO)2(Bitianp)]. This compound was characterized by elemental analysis, IR, 1H-, 13C- and 31P-NMR spectroscopies. The structure of nickel complex has been determined by X-ray crystal-lography. Crystal data for C42H28NiO2P2S2 (M = 749.41 g/mol): triclinic, space group P-1 (no. 2), a = 10.539(2) Å, b = 11.811(2) Å, c = 15.994(3) Å, α = 83.93(3)°, β = 88.18(3)°, γ = 65.24(3)°, V = 1797.6(7) Å3, Z  = 2, T  = 294(2) K, μ(MoKα) = 0.781 mm-1, Dcalc =1.385 g/cm3, 22744 reflections measured (2.56° ≤ 2Θ ≤ 64.726°), 11837 unique (Rint = 0.0157, Rsigma = 0.0215) which were used in all calculations. The final R1 was 0.0360 (I > 2σ(I)) and wR2 was 0.1088 (all data). The coordination sphere of the Ni center is best described as a tetrahedral geometry.
