A homoleptic lanthanide guanidinate complex [(CH_2)_5NC(N~iPr)_2]_3Yb was synthesized by the metathesis reaction of lithium guanidinate with anhydrous YbCl_3 in 3∶1 molar ratio in THF.Its crystal structure was determined by X-ray diffraction.The crystallographic data:C_(36)H_(72)N_9Yb,Mr=804.07,orthorhombic,space group P2_12_12_1(#19),a=10.3168(7),b=11.443(7),c=35.5649(2)?,V=4199.1(5)?~3,Z=4,Dc=1.272 g/cm~3,F(000)=1684.00,T=193.1K,λ(MoKα)=0.7107?,μ=22.61 cm~(-1),R=0.040,wR=0.126 for 8653 observed reflections with(I>3.00 σ(I)).The ytterbium is six-coordinate by six nitrogen atoms of three chelation bidentate guanidinate ligands.
