| 摘 要： | The title complex L3Y(L = [O-4,6-di-tBu-C6H2-2-CH{CH(iPr2NCHCHN) }]) has been synthesized by the reaction of LiY[N(iPr) 2]4 with H2LCl and LiBu in a 1:3:2 molar ratio at 0 ℃ in THF,and characterized by single-crystal X-ray diffraction. It crystallizes in monoclinic,space group P21 with a = 14.3612(16) ,b = 14.7524(14) ,c = 16.898(2) ,β = 105.708(3) o,V = 3446.3(6) 3,Mr = 1203.50,Z = 2,Dc = 1.160 Mg/m3,μ(MoKα) = 0.90 mm-1 and F(000) = 1296. The structure was refined to R = 0.050 and wR = 0.110 for 10213 observed reflections with I > 2σ(I) . The Y ion is coordinated to three phenoxo groups and three NHC ligands to form a distorted octahedral geometry. The temperature effect on the reaction leads to the 1,2-benzyl migration of NHC ligand to form the title complex. |

| Abstract: | The title complex L3Y (L=[O-4,6-di-tBu-C6H2-2-CH{CH(iPr2NCHCHN)}]) has been synthesized by the reaction of LiY[N(iPr)2]4 with H2LC1 and LiBu in a 1:3:2 molar ratio at 0 ℃ in THF, and characterized by single-crystal X-ray diffraction. It crystallizes in monoclinic, space group P21 with a=14.3612(16), b=14.7524(14), c=16.898(2) (A),β=105.708(3)°, V= 3446.3(6) (A)3, Mr=1203.50, Z=2,Dc= 1.160 Mg/m3, μ(MoKα)=0.90 mm-1 and F(000)=1296. The structure was refined to R=0.050 and wR=0.110 for 10213 observed reflections with I ＞ 2σ(I). The Y ion is coordinated to three phenoxo groups and three NHC ligands to form a distorted octahedral geometry. The temperature effect on the reaction leads to the 1,2-benzyl migration of NHC ligand to form the title complex. |
