摘要
A neutral homoleptic lanthanide amide Yb(NPh 2) 3(THF) 2 was obtained by reaction of anhydrous YbCl 3 with LiNPh 2 in THF. The product was characterized by elemental analysis, infrared spectrum and X-ray crystallographic analysis. The crystal data are monoclinic, P2 1/n space group, a=1.2052(2) nm, b=1.9369(3) nm, c=1.6523(2) nm, β=92.79(1)°, V=3.8524(9) nm 3, Z=4, D c=1.417 g·cm -3, μ=24.67 cm -1 (Mo Kα), F(000)=1668, R=0.036, R w=0.039. The central metal ytterbium is coordinated by three terminal NPh 2 groups and two THF molecules to form a five-coordinate distorted trigonal bipyramid. The mean Yb-N bond length is 0.2219(6) nm.
