摘要
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 P , a = 9.135(1), b = 9.772(1), c = 17.000(2) , a = 76.377(2), b = 78.333(2), g = 67.243(2)? Mr = 582.44, V = 1349.7(3) 3, Z = 2, Dc = 1.433 g/cm3, m(MoKa) = 0.581 mm-1 and F(000) = 596. A total of 5614 reflections were collected in the range of 2.30< q < 25.03? of which 4721 were independent (Rint = 0.0176) and 4159 observed reflections (I ≥ 2s(I)) were used in the refinement. R = 0.0326 and wR = 0.0867. The Mo centre is six-coordinated by four carbonyls (MoC 1.938(4), 2.003(4), 2.019(4), 2.035(4) ) and P, N atoms from the ligand (MoP 2.4812(8), MoN 2.349(3) ?. The coordination geometry of the complex can be described as an octahedron.
