| 摘 要： | In recent years,the synthesis of polyisocyanatesand their chemical structures have received consider-able attention,because polyisocyanates have somespecial properties,such as chiral spiral structure1]and liquid crystal2]etc.We previously reported thatcyclopentadienyl lanthanide amido complexes3]anddivalent lanthanide complexes4]both can catalyze theoligomerization or polymerization of phenyl isocyanate.Furthermore,the active intermediates of these reac-tions were obtained by the stoichiom…

| Abstract: | Bis (methylcyclopentadienyl) lanthanide amido complex (MeCp)2YbNPh2 (THF) reacted with n-hexyl isocyanate (n-HexylNCO) in 1:1 molar ratio to give {(MeC5H4)2YbOC(NPh2)N(n-hexyl)] }2(1). Complex 1 was characterized by elemental analyses and X-ray diffraction. The title complex belongs to trigonal system and R-3 space group. Its unit cell parameters are a = 2.9533(11) nm, b = 2.9533(11) nm, c = 1.5873(6) nm, V = 11.9896(80) nm3, Z = 9,with two symmetrical bridged oxygen atoms. Nitrogen atom is coordinated to the ytterbium atom to form a tricyclic backbone. The coordination number of ytterbium is 9. The whole molecule shows central symmetry. |
