Synthesis and Crystal Structure of Mo(CO)4(NNP) (NNP = 2-(N-Cyclohexyl-N-diphenylphosphinomethyl)aminopyridine)
The crystal structure of the title complex, Mo(CO)4(NNP), (NNP=2-(N-cyclohexyl-N-diphenylphosphinomethyl)aminopyridine) has been determined, and its crystallographic data are as follows: triclinic, space group P1-, a = 9.135(1), b = 9.772(1), c = 17.000(2) (A), α= 76.377(2),β= 78.333(2), γ= 67.243(2)°, Mr= 582.44, V = 1349.7(3) (A)3, Z = 2, Dc = 1.433 g/cm3,μ(MoKα) =0.581 mm-1 and F(000) = 596. A total of 5614 reflections were collected in the range of 2.30＜θ＜25.03°, of which 4721 were independent (Rint = 0.0176) and 4159 observed reflections (Ⅰ≥ 2σ(Ⅰ))were used in the refinement. R = 0.0326 and wR = 0.0867. The Mo centre is six-coordinated by four carbonyls (Mo-C 1.938(4), 2.003(4), 2.019(4), 2.035(4) (A)) and P, N atoms from the ligand (Mo-P 2.4812(8), Mo-N 2,349(3) (A)). The coordination geometry of the complex can be described as an octahedron.
