| Abstract: | The title compound dichlorobis(tribenzylphosphine)nickel(II), Ni[P(CH2C6H5)3]2Cl2, belongs to a type of tertiary phosphine coordination complex, M(PR3)2X2. There are two molecules in the unit cell which do not appear to interact chemically. Both molecules have a trans-square planar configuration with each nickel atom on a center of symmetry. Three benzyl groups are bonded to each phosphorus atom as rotors in a propeller, and the threefold axis is along the P—Ni bond, which has a mean length of 2.23(1) Å. Crystal data: C42H42Cl2NiP2, Triclinic, space group  , a = 10.4892(15) b = 10.5249(12) c = 19.453(2) Å,  = 83.872(8),  = 76.839(9),  = 62.241(8)°, V = 1850.5(4) Å3, Z = 2. There is an intramolecular hydrogen bond between the C3 and C11 atoms. |
